4. File Manager

4.1 Overview
The functionality and structure of the "File Manager" on the U2 are similar to "Windows Explorer" on a PC. To run the "File Manager", press F from the "Program" menu or press "Enter" when your cursor is placed on "File Manager". You can launch the "File Manager" from anywhere on the unit by pressing "WIN-F". Close the "File Manager" by pressing "Alt-F4".
The "File Manager" contains 2 basic areas: an "address window" and the content list. You can navigate between them using "Tab" and "Shift-Tab". When you first open the "File Manager", you are placed in the drive list. By default, you are placed on the internal "flashdisk". If an SD card or USB drive is connected, it also appears in the list. You can use The Up or Down arrow or the scroll buttons to navigate the items in the drive list. Press "Enter" on the drive you want to open. The U2 then displays the list of the files/folders on that drive. 
The "address window" contains the path of the current directory or file. 
The "File Manager" contains both menus and hot keys, allowing you to easily activate items in the program with a single keystroke as well as to access functions through the menus for commands you have not memorized. You can bring up the menus by pressing "Alt". 
Use Up Arrow" and Down arrow" to navigate among the available menus. To open a menu, press "Enter". Again, use The Up or Down arrow to navigate among the items in a menu, and press "Enter" to execute a menu item.
The File Manager also contains dialogs. You can navigate among the controls in a dialog box by using "Tab" and "Shift-Tab".
   
4.1.1 Navigating the File List
The "File Manager" contains two kinds of lists: the "file list" and the "menu list", or rather, the list of items contained in the "File Manager" menu. The menus in the U2 wrap. This means, when you reach the end of the list of items in a menu, the U2 automatically brings you back to the top of the list when you press the Down arrow. However, when you reach the end of a "file list," the U2 remains at the end of the list, even if you press the Down arrow. The following is a list of the keystrokes used for navigating lists:
* Note: the following keystrokes can be used to navigate any list on the U2.
1. Move to previous item: (Up Arrow) or up scroll button
2. Move to next item: (Down arrow) or down scroll button
3. Move to the beginning of a list: Control-Home
4. Move to the end of a list: Control-End
5. The following keystrokes are valid only in a "file list".
6. Jump to folder or file list: Control-Down arrow
7. Move between file list and address window: Tab or Shift-Tab
8. Enter the selected folder or open the selected file: Enter
9. Move back a level in the folder structure: Backspace
10.  Jump to the drive list: Shift-Backspace
11.  Move to the previous group of 32 items: Page up 
12.  Move to the next group of 32 items: Page down 
13.  Jump to a file or folder by pressing the first character of the folder or file name. 

4.1.2 Selecting folders and files
1. Select individual items "Space": * is displayed in front of the item to denote its selection. Pressing "Space" again on the selected folder or file cancels the selection.
2. Continuous selection ("Control-b") This selects all of the items from the point where this command is executed to the item where the cursor is located. * appears in front of the selected items.
3. Select all ("Control-a") This selects all the files and folders in the current list. You can  toggle selection and de-selection  of items by pressing "Space". When the "Select All" command is executed, the U2 says the number of selected files, and * appears in front of the selected files on the Braille display. 

4.2 Working with Files and Folders
When viewing the contents of a drive or folder, the items in quotation marks are folders, and the items without quotation marks are files. 
The items in the list are followed by numbers, such as 1/5 or 2/5. The numbers following the items indicate an item's placement in the list and the total number of items in the list. For example, "database 1/5," indicates "database" is the first folder in a list containing five items.

4.2.1 Entering and Exiting Folders
There are several ways to open a folder. 
1. Bring up the menu by pressing "Alt". Select the "Open" option from the list and press "Enter". 
2. Press the hot key "Control-O" to activate the "Open" command and open the desired folder.
3. Finally, as described above, you can simply press "Enter" on the selected folder.
To exit the current folder, use the "Backspace" key. You are returned to the previous level in the folder structure. 

4.3 The File Menu.
To open the "File" menu, press "Alt" to bring up the menu, and press "Enter" on "File". Use normal list commands to navigate to your desired option and press "Enter".

4.3.1 Opening a File
You can open a file by pressing "Enter" on the selected item or by pressing "Control-O" to open a file or folder. The U2 automatically loads the appropriate application or program to open the chosen file. You can also open a file by selecting "Open" from the "File" menu.
The U2 supports the following file formats: 
1. Document files: hbl, brl, txt, pwd, brf, rtf, doc/docx, XLS/XLSX, PPT/PPTX, PDF and unprotected EPUB.
2. Web formats: url, and html. 
3. Media formats: ac3, asf, asx, m3u, mp2, mp3, ogg, pls, wav, wax, wma, wmv and flac. 
4. DAISY formats: DAISY 2.0, 3.0, Learning Ally, BookShare, NLS, and Open Library 

4.3.2 Open With
If you press "Enter" on a file type other than those mentioned above, the "Open With" dialog box appears, because the file type is not associated with a program. You can also select the "Open With" option in the "File" menu to open the currently selected file with a program other than the one originally associated with that file type. Or, press "Control-H" to open the dialog from the file list. 
This dialog box consists of the "Open With" list, the "adopt" list, a "Confirm" button, and a "Cancel" button. You can move between these elements by pressing "Tab" or "Shift-Tab". 
When the dialog box opens, "Open with: Word processor" is displayed. In this list, you can select a program, the Word Processor, Media Player, or Web Browser.  Once you have selected the program with which to open the file type, "Tab" to the "adopt" list. If you have selected the Word Processor, you are taken to an additional list called "Open mode". Using this list, you can specify whether the file is opened as a Braille file or a text file.  Select the file type, then "Tab" to the "Apply to" radio button. Use this radio button, to specify whether only the current file or all of the files with this extension are opened with the specified program. After setting your preference, press "Enter" or "Tab" to the "Confirm" button, and press "Enter" to apply the settings. If you have specified a program that does not support the file type, nothing is displayed or played after the program is launched.
If you activate the "Open With" menu after focusing on folders that have DAISY or media files, the associated program, DAISY or Media Player is displayed. If you activate the "Open With" menu, and encounter a folder that does not have the DAISY info file (discinfo.html or ncc.html), the DAISY Player is not displayed as an associated program. You can play all of the files after selecting either the DAISY or Media Player.

4.3.3 Open in Second Word Processor or Document Reader.
By default, if you press "Enter" on a file supported in the Word Processor, it launches the default Word processor on the unit. However, you can open files in a second "New Word Processor", so that you can more easily switch between documents. To do this, select "Open in New Word processor" from the "File" menu when a document file is focused in the  list. You can also activate this function by pressing "Alt-W". 
You can also choose to open the focused file in the Document Reader instead of the Word processor or Web Browser. To do this, select "Open in Document Reader" from the "File" menu or press "Alt-R".

4.3.4 Zip
With this function, you can compress files and folders into a zip file. Compressing a file makes the total file size smaller, making it easier to email, or to save space on a storage device. To use the "Zip" function, Select the files or folders you want to compress. Then, select "Zip" from the "FILE" menu or press "Control-Z" from the file list. 
U2 prompts, "Zip filename: (default filename.zip)". "Default filename" is the file name that is used for the compressed file if you try to compress only one file or folder. If you try to compress several files or folders, the default name is the folder name that contains the files and folders.
Press "Enter" to zip the file under the default name, or type a new name and the edit box and press "Enter" and the zip file is created in the current directory. To cancel, press "Escape" or "Alt-F4".
  
4.3.5 Unzip
The "Unzip" function allows you to unzip (or decompress) a zip file. To activate the "Unzip" function, navigate to the file you want to unzip and select "Unzip" from the "File" menu, or press "Control-U" directly from the file list.
U2 prompts, "Unzip to folder name: (default folder name)". The default folder name is the same as the compressed file name. For example, if you unzip a file called "test.zip," "unzip folder name: test" is displayed.
Press "Enter" to accept the folder name, or type a new name in the edit box and press "Enter". The U2 unzips the files to the specified folder. Press F 4" or "Alt-F4" to cancel the unzipping process.  
* Note: You can also initiate the unzip process simply by pressing "Enter" on a zip file.

4.3.6 Send To
Use this option to copy files and folders to different drives such as a USB flash drive or an SD card. After selecting files and folders, select "Send To" from the "File" menu or press "Control-S" from the file list.  The U2 displays the list of drives that you can send your files or folders to. Choose a destination drive using The Up or Down arrow. Pressing "Enter" on the desired drive starts the copying of the selected files and folders to the selected drive.  

4.3.7 Rename
Use this function to change the name of a file or folder. Move to the item you wish to rename, and select "Rename" from the "File" menu or press "F2" directly from the file list.  The U2 asks for a new name. On the Braille display, "New file (or folder) name: (current file/folder name)" appears. You must type the new file/folder name. Press "Enter" after entering a new file name to complete the renaming process.
You cannot use the following characters in a file name or folder: "|, \, <, >, ?, :, *"

4.3.8 New Document
Use this option to create a new document. Select "New Document" from the "File" menu, or press "Control-N" from the file list.  
The U2 displays "File type: text (txt)". You can create two types of documents: text files and Braille files. Use the Down arrow to select the "Braille (brl)" file format. When you press "Enter" on either "text (txt)" or "Braille (brl)," the U2 displays "New document name: New Document0.txt" or "New Documen0.braille". "New Document0.xxx" is the default file name based on the file type you have chosen. The number after the new document increases by one whenever you create a new document for which you do not specify a name. You can also type in the document name you prefer and
 press "Enter". The new document you named is created. "|, \, <, >, ?, :, *" characters cannot be used when creating a file name.

4.3.9 New Folder
Use this option to create a new sub-folder under the current folder. Select "New Folder" from the "File" menu, or press "Alt-F" directly from the file list.  
The U2 prompts, "New folder name:,". Enter your preferred new folder name, and press "Enter". Your new folder is created.  
When creating a new folder name, you cannot use the following characters: "|, \, <, >, ?, :, *"

4.3.10 File Conversion
The "File conversion" function is similar to the "Save As" function in the Word Processor. This feature converts files to different file formats. The U2 file conversion feature supports the following file formats: "Sense Word (hbl)," "Text (txt)," and "Braille (brl)".
The U2 can convert a single file or multiple files at once to your preferred file format. After selecting the files you want to convert, select "File Conversion" from the "File" menu or press "Control-T" directly from the file list.   
The U2 prompts you to choose the preferred file format. Use The Up or Down arrow to select the desired file format. Press "Enter" and the U2 begins converting files to the file format you have chosen. The U2 keeps the original file names for the files you have converted, except for the file name extension which reflects the new file type. If a file with the same name and extension already exists, "date" and "time" are added to the file name. 

4.3.11 Search for File
Use the "Search for File" function to locate a file or folder for which you know all or part of the name, but not the location. Select "Search for File" from the "File" menu, or press "Control-F" from the file list.  The U2 displays the "file to find" dialog box. 
The dialog box consists of the "edit box for entering the text of the name to search", a "combo box to select the current folder or a drive", "check box enabling to choose whether or not to search sub-folders", a "search button", a "cancel button" and the results list. Use "Tab" and "Shift-Tab" to move through the controls.
U2 prompts "File to find:" you are placed on the edit box for entering the file name to search". Type all or part of the file name and press "Enter". U2 searches for all files containing the text you entered. When the file search is complete, you are placed in the results list. 
If you press "Enter" on a file, you are placed on the path where the file is stored and the file search dialog box is closed. You can open the file by pressing "Enter" on the file name again.
If you want to search for a file in just the current folder or on another drive, after typing the file name, Tab to the "Search in" combo box. Navigate to your desired search target. If you press "Enter" either on a specific drive or on the "Search button," U2 searches that location for files matching the text you entered in the edit box. 
The drive list displays all storage devices currently connected to the U2. If there are many files in a drive, it can take some time to perform a search. While the search is being performed, "searching" is displayed to alert you to the fact that the search is active.  
To search the root of the current folder or a drive excluding sub-folders, Tab to the "Search sub-folders" check box. Press "Space" to uncheck this option, and press "Enter". By default, U2 includes sub-folders when you search for files. 

4.3.12 Search for Text
Use the "Search for Text" function to locate a file in which you know some of the text, but not the title or the location. Select "Search for Text" from the "File" menu, or press "Alt-C" from the file list.  The U2 displays the "Text to find" dialog box. 
The dialog box consists of the "edit box for entering the text to search", a "Match Case" checkbox, a "File Type" combo box, "combo box to select the current folder or a drive", "check box enabling to choose whether or not to search sub-folders", a "search button", a "cancel button" and the results list. Use Tab and Shift-Tab to move through the controls.
U2 prompts "Text to find:" you are placed on the edit box for entering the text string to search". Type the text  and press "Enter". U2 searches for all files containing the text you entered. When the file search is complete, you are placed in the results list. 
If you press "Enter" on a file, you are placed on the path where the file is stored and the file search dialog box is closed. You can open the file by pressing "Enter" on the file name again.
If you want to search for a file in just the current folder or on another drive, after typing the file name, Tab to the search "File Type" combo box. You can search text in Text files, Braille files, MS Word files, RTF files, or all of those file types.
After selecting the file type, Tab to the "Search in" combo box. Navigate to your desired search target. If you press "Enter" either on a specific drive or on the "Search button," U2 searches that location for files matching the text you entered in the edit box. 
The drive list displays all storage devices currently connected to the U2. If there are many files in a drive, it can take some time to perform a search. While the search is being performed, "searching" is displayed to alert you to the fact that the search is active.  
To search the root of the current folder or a drive excluding sub-folders, Tab to the "Search sub-folders" check box. Press "Space" to uncheck this option, and press "Enter". By default, U2 includes sub-folders when you search for files. 

4.3.13 Information
Use this option to query information about files and folders. Select "Information" from the "File" menu or press "Alt-Enter" from the file list.  
The U2 displays the information about a file or folder in the following order:   
1. File type: Displays the file format information, such as "brl file," "doc file," or "txt file". When a folder is selected, this area indicates that the item is a folder containing x number of files and folders.
2. File size: displays the size of the selected file or folder. When multiple files or folders are selected, this area displays the total size of the selected files and folders.
3. Date and time: Displays the time and date the folder/file was created or modified.
4. Attribute: Displays whether the file is write protected or is writable. You can change this attribute  by pressing "Space." When multiple files or folders are selected, this attribute is not shown.
5. Confirm: To change the attribute, press "Enter" on "Confirm". 
6. Cancel: To cancel the change, press "Enter" on the "Cancel" button. 
7. You can also press "Alt-Enter" from the File Manager or "Program" menu to hear how much space is available on the flashdisk.

4.4 The Edit menu.

4.4.1 Copy / Move
"Copy" leaves the selected files and folders in their original locations, and creates copies of them in your chosen destinations. "Move" removes the selected files and folders from their original locations, and moves them to the new locations you have chosen.
Use the copy/move function as follows:
1. Select the files and folders you wish to copy. 
2. Select "Copy" or "Cut" from the "Edit" menu. You can also press "Control-C" to "Copy" or "Control-X" to "Cut" from the file list. 
3. Navigate to the destination folder.
4. Choose "Paste" from the "Edit" menu. Your selected files and folders are copied or moved. "Control-v" executes "Paste" directly from the file list. 
If the destination folder is the same as the source folder, the U2 attaches "Copy1" to your original file names. If the same files are copied into the same folder a second time, the U2 attaches "Copy2" to the original file names. 
If your destination folder has the same name as the file you are copying, the U2 prompts "File xxx already exists. Overwrite? Yes". Press "Enter" if you want to replace the file. If you do not want to overwrite the file, select "No," and press "Enter". When "No" is selected, the "Paste" function is canceled.

4.4.2 Delete Files or Folders
Select the items you want to delete, and choose "Delete" from the "Edit" menu or press "DEL" from the file list.  
When you delete only one item, it is not necessary to use the select function. Instead, simply navigate to the file or folder and delete it as described above.  

4.4.3 Select All
This feature selects all the files and folders in the current list.  Choose "Select All" from the "Edit" menu, or press "Control-A" to select all the items in the current list. The U2 says, "x objects selected".  
An * appears in front of each file name you have selected. You can cancel the selection of a file or folder by pressing "Space". This feature is a convenient method for selecting multiple files for copying, cutting, or deleting. 

4.5 The View Menu.

4.5.1 Sort Files 
This option is used to specify the order in which files and folders are displayed in the file list. Select "Sort Files by" from the "View" menu or press "Control-G" from the file list.   
Files and folders can be sorted according to the following: "Name," "Size," "Extension," and "Date and Time".  Press "Enter" after selecting the sorting criterion, and files and folders are displayed in the specified order. If you select "Name" or "Extension," the list is sorted in ascending order, and if you select "Size" or "Date and Time," the list is sorted in descending order. By default, files and folders in the file list are sorted by "Name" with folders appearing at the top of the list, and files appearing at the bottom. 

4.5.2 Set File Info
This item is used to set what kind of information is displayed for each item in the file list. Select "Set File info" from the "View" menu, or press "Control-L" directly from the file list.    
The available options are, "Name," "Name, Size," and "Name, Size, Date and Time".  Press "Enter" after selecting the information to be displayed, and the file list is updated, showing the information you specified. By default, only names are displayed in the "file list". If you have selected "Name, Size," the name and size of files are displayed. However, for folders, size is not displayed.  
This option remains effective until a Hard Reset is performed.

4.5.3 Display only Files of Type
This is used to specify what type of files are displayed in the file list. Choose "Display only Files of type" from the "View" menu, or press "Control-W" from the file list. 
Choose which files are displayed by selecting one of the following items: "All Files," "Sense Word Files," "MS Word Files," "Text Files," "Braille files," "HTML Files," "URL Files," "Media Files," and "Wave Files".  Press "Enter" after selecting the file type you want, and only the files of the specified type are displayed in the file list. Folders are displayed no matter which type you have specified. By default, all files are displayed in the file list. This setting remains in effect only until you close the "File Manager," so all the files are displayed when you re-open it.

4.6 Network menu.
The network file sharing function enables you to share files between your U2 and other devices connected to the same network.   
You can copy files on the Braille Sense from other computers on the network, edit files on other computers with the Word Processor or even open media files on other devices and play them in the Media Player on the U2.  You can also share folders on your U2 and access them from other computers connected to the network. 
You can share files over a network using LAN or WIRELESS LAN. When using LAN, once the U2 is connected, you can easily find and access the shared files of other computers connected to the network. 
However, when using wireless LAN, it is only possible to access shared files when your U2 and the connected computer are at the same layer. This means that you can't search for a computer connected to router A if you are connected to router B, a wireless LAN sub-connection of router A. 
For more detailed information on LAN/WIRELESS LAN configurations, refer to the "Setup Internet" section of the "Utilities" chapter in this user manual. 

4.6.1 Search for shared computers and add to the network list.
When you open the "File Manager", network is displayed in the drive list. The network list consists of the shared folders on computers connected to your network that you have added to the network list. From the network list, you can open the shared folder, or delete the network location from the list. If you have not added shared folders, this list is empty.  
To search shared computers connected to the network, Use the "Network Connection Setting" dialog to search for computers with shared content. You can open this dialog by pressing "Alt-E" from anywhere in the File Manager or by selecting it from the "Network" menu.  
The "Network Connection Setting" dialog box contains the following controls: "Remote name" computer edit box, "Remote folder" list box, "Add/Remove" button and a "Cancel" button.
You are placed on the "Computer name" edit box. Type the computer name with or without backslashes and press "Enter".
If the shared computer is found, a login prompt may be displayed according to the shared computer setting.
If the computer is running Windows vista or Windows 7, you must enter the folder path as shown below. 
Ex) "\\hims\sharing", "hims\music"
* Note: if the shared folder name exceeds 11 characters, it cannot be recognized by the U2. 
If the computer you are trying to access does not have a network user name and password specified, type "guest" in the Login edit box and press "Enter". If the computer requires a specific network user name and password, make sure they are entered correctly. If login is successful, you are placed in the Remote Folder list and the folders shared on that computer appear in the list.
Move to the desired folder in the list and press "Enter" on the "Add" button. The network location of the shared folder is added to the network list in the File Manager. You may select as many folders as you wish from the Remote Folder list and add them to the network list.
Once the network locations of the shared folders have been added to the list, they are accessible from the "network" option in the File Manager as long as you are connected to the network where they reside. In other words, if you have added a location for a shared folder on your home network, you cannot access this location from your office as you are no longer connected to the home network on which the shared folder is located. Also remember that you cannot access shared folders on a network if you do not have a wireless or LAN connection to that network. 

4.6.2 Remove Remote folder 
There are 2 ways to remove a remote folder from the File Manager's network list.  From the network list, navigate to the remote folder you want to remove and press "Alt-U".  Or, you can press "Alt-E" to open the "network connection setting" dialog, navigate to the remote folder you want to remove, "Tab" to the "Remove" button and press "Enter". 

4.6.3 Share Folder On Network 
The Braille Sense allows you to share folders over a network, so that you may access them from other devices. After selecting a folder you want to share, choose "Share Folder on network" from the "Network" menu, or press "Alt-S" from the file list. The Braille Sense prompts, "Folder successfully shared, please reset your Braille Sense", as you must reset for the share to take effect. If a folder is shared, this menu item reads "Do not share this Folder". You can unshare a folder by selecting it and choosing the "Do Not Share this Folder" item from the menu, or by pressing "Alt-U."

4.6.4 Set Local Security 
If you have chosen to share folders over a network, you may wish to require a username and password for access to the folder in order to ensure others cannot gain unauthorized access to the shared folders on your Braille Sense. To secure your folder, select the folder and choose "Local Security Settings" from the "Network" menu, or press "Alt-P" from the folder list.   
The "Local Security Setting" dialog contains 4 items: "Username" computer edit box, "Password" computer edit box, a "Confirm" button, and a "Cancel" button. You can move among the items using "Tab" and "Shift-Tab". 
To secure your folder with a username and password, type the username and password you wish to use into the respective computer edit boxes. Press "Enter" to save your settings, or Tab to "Confirm" and press "Enter". If you do not wish to save your settings, Tab to "Cancel" and press "Enter" or press "Escape" or "Alt-F4".  

4.7 EML Viewer
The U2 allows you to view and interact with e-mail message files directly from within the File Manager. E-mail messages created and received using the E-mail program on the Braille Sense are stored in the "E-mail" folder on the unit's flashdisk. The e-mail folder contains "pop3" and "Imap" folders consisting of subfolders for each account in that category. Each account folder contains folders for each mailbox, which, in turn, contain the message or "EML" files. 
At times, you may find it more efficient to access a specific e-mail using the File Manager as you do not have to wait for the e-mail program to load the mailboxes, etc. Use normal file and folder navigation as described previously to access the EML file, or rather, the message you wish to locate. When you have located the message you wish to open, you can open it in the EML Viewer by pressing "Enter". 
The EML Viewer opens the message, and places you in the message body. The "EML Viewer" dialog contains 7 controls: "Subject" static box, "Date" static box, "From" static box, "Message Body" multi-line edit box, ""Attach" file list box (only appears if message contains attachment), Forward" button, "Reply" button, and "Close" button. You can move among the controls using "Tab" or "Shift-Tab".  
From within the Message body, use normal file reading commands to navigate the message. (See section 5, Word processor for more details) You may also forward or reply to a message from the EML Viewer. To forward a message, tab to the "Forward" button and press "Enter" or press "Control-F" from within the message. To reply to a message, tab to the "Reply" button and press "Enter" or press "Control-R" from within the message. 
When either "Forward" or "Reply" is launched, you are placed on the "To" field of a new message dialog. Create the forwarded or reply message just as you would in the U2's "E-mail" program. (See section 6 of this manual.)
To close the EML file/message and return to the file list, tab to the "Close" button and press "Enter" or press "Alt-F4". 

4.8 Using the Address Window
This edit box lets you type the direct path of the file name you want to open. This window also contains the history list for easily accessing recently opened files or directories. 
When you are in a file or folder list, you can press "tab" to navigate to the address window. The U2 displays the current path including the current drive name, such as "flashdisk/download/".  The address window is only visible when you are in a file or folder list. When you are in the drive list, the address window is not available.
You can edit the text by relocating the cursor with a cursor routing key, the U2 inserts the text at the cursor location. If you know the exact path and file name, you can type in the path and file name to open the file with the appropriate application. For example, if you type in "flashdisk/download" in the address window and press "Enter," the U2 displays the list of the files in the download folder. If you type "flashdisk/My Documents/sample.txt" in the address window, and press "Enter," the U2 loads the Word Processor, and opens the file "sample.txt". 
Use The Up or Down arrow in the Address Window to review the history list (a list of file and folder paths you have recently opened). To open a file in the history list, press "Enter". The file opens with the appropriate application. (See section 4.2.3).
