4. File Manager

4.1 Overview

The functionality and structure of the "File Manager" on the Braille Sense U2 are very similar to "Windows Explorer" on a personal computer. To run the "File Manager", press "f (dots 1-2-4)" 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 "F1-F".
The "File Manager" contains 2 basic areas: an "address window" and a "file list". When you first open the "File Manager", you are placed in the drive list. By default, you are placed on the internal flash drive, named "flashdisk". You can use the up and down arrows ("Space-1" or "Space-4") or the scroll buttons to navigate the items in the drive list. Press "Enter" on the drive you want to open. The Braille Sense U2 then displays the list of the files/folders on the drive you have opened.
When you press "tab (Space-4-5 or F3)" or "shift-tab ("Space-1-2" or "Space-F3")" on the "file list," you enter the "address window". The "address window" contains the path of the current directory or file. 
For your convenience, 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 access and select a function through the menus even if you have not memorized the associated keystroke. YOU can bring up the menus by pressing "Space-m (dots 1-3-4)" or "F2". 
WARNING!! The Braille Sense U2 makes it possible to format the flashdisk to solve corruption problems and/or start over with a clean internal drive. Formatting the flashdisk erases everything on the flashdisk. Be extremely cautious when executing this command. If you execute this command, you will lose all of your data. You will NOT be able to retrieve this data once the command is executed. To format the flashdisk, press and hold "Space-1-2-3". While holding down "Space-1-2-3," quickly press and release the reset button. Continue holding "Space-1-2-3" until you hear the "format start" announcement.

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 Braille Sense U2 wrap. This means, when you reach the end of the list of items in a menu, the Braille Sense U2 automatically brings you back to the top of the list when you press "Space-4". However, when you reach the end of a "file list," the Braille Sense U2 remains at the end of the list, even if you press "Space-4". The following is a list of the keystrokes used for navigating lists:

1. Move to previous item: Up arrow key (Space-1) or up scroll button
2. Move to next item: Down arrow key (Space-4) or down scroll button
3. Move to the beginning of a list: Ctrl-home (Space-1-2-3)
4. Move to the end of a list: Ctrl-end (Space-4-5-6)

The following keystrokes are valid only in a "file list".

1. Jump to folder or file list: Space-5-6
2. Move between file list and address window: Tab (Space-4-5 or F3) / shift-tab (Space-1-2 or Space-F3)
3. Enter the selected folder or open the selected file: Enter
4. Move back a level in the folder structure: Backspace
5. Jump to the drive list: Space-1-2-5-6
6. Move to the previous group of 32 items: Page up (space 1-2-6 or F1-F2)
7. Move to the next group of 32 items: Page down (space 3-4-5 or F3-F 4)
8. Jump to a file or folder by pressing the first character of the folder or file name. You must use ASCII characters.

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 ("Enter-b (dots 1-2)"): 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 ("Enter-a (dot 1)"): This selects all the files and folders in the current list. You can use navigation keys to move among the selected items to check their selection status. You can cancel selections or reselect de-selected items by pressing "Space". When the "Select All" command is executed, the Braille Sense U2 says the number of selected files, and * appears in front of the selected files on the Braille display. 

4.1.3 Cancel / Exit

Cancel ("Space-e (dots 1-5)" or "F 4"): Cancels a function, just as the "esc" key cancels functions on a personal computer.
Exit ("Space-z (dots 1-3-5-6)"): Cancels or stops a selected function or program. This is similar to the way "alt-F 4" closes a program on a personal computer.

4.2 Working with Files and Folders

When you open the "File Manager," the list of available drives is displayed. Navigate to the drive you wish to access, and press "Enter" to open it. The Braille Sense U2 displays the list of folders and files on that drive. 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 Selecting drives

When you open the "File Manager," the first item in the list is "flashdisk". If an SD card or USB flash drive is inserted, it also appears in this list. Navigate to and select a drive by using the up and down arrows ("Space-1 or Space-4") or the scroll buttons. After selecting your desired drive, press "Enter" to open it. 

4.2.2 Entering and Exiting Folders

There are several ways to open a folder. You can utilize the menu to open a specific folder.
1) Bring up the menu by pressing "Space-m (dots 1-3-4)" or "F2". Select the "Open" option from the list and press "Enter". 
2) You can also press the hot key "Enter-o (dots 1-3-5)" 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. 

4.2.3 Opening a File

You can open a file by pressing "Enter" on the selected item. You can also use "Enter-o (dots 1-3-5)" to open a file or folder. The Braille Sense U2 automatically loads the appropriate application or program to open the chosen file. 
You can also open a file by using the menu. Press "Space-m (dots 1-3-4)" or "F2" to open the menu. Then, press the letter "o (dots 1-3-5)," or press "Enter" on "Open".
The Braille Sense U2 supports the following file formats: 

1. Document files: hbl, brl, txt, pwd, brf, rtf, doc/docx, XLS/XLSX, PDF and unprotected EPUB files are supported in the Word Processor. 
2. Web formats: url, and html files are supported by the Web browser. 
3. Media formats: ac3, asf, asx, m3u, mp2, mp3, ogg, pls, wav, wax, wma, wmv and flac files are supported by the Media Player. 
4. DAISY books, including those from BookShare, NLS, and Open Library are supported by the DAISY player. 

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 bring up the "Open With" dialog box using the menu. By using the "Open With" menu option, you can open the currently selected file with a program other than the one originally associated with that file type. First, press "Space-m (dots 1-3-4)" to bring up the menu. Navigate to "Open With," and press "Enter". You can jump quickly to this option in the menu by pressing "e (dots 1-5)". You can also open the dialog box by pressing "Enter-e (dots 1-5)" 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 (Space-4-5)" or "shift-tab (Space-1-2)". Within the list, you can select the next item by pressing "Space-4," and the previous item by pressing "Space-1".
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. Pressing "Space-4" selects the next program, and "Space-1" selects the previous program. Once you have selected the program with which to open the file type, press "tab (Space-4-5)" to move to the "adopt" list. If you have selected the Word Processor, pressing "tab (Space-4-5)" takes you 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. Press "Space-4" or "Space-1" to select one of the two file types, then press "tab (Space-4-5)" to move to the "Apply to" radio button. Use this radio button, to specify whether only the currently selected file or all of the files with the same file extension are opened with the specified program. After setting your preference, press "Enter" or "tab (Space-4-5)" to move to the "Confirm" button, and then 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.

4.2.4 Send To

You can use this option to copy files and folders to different drives such as a flash drive, USB flash drive (also known as USB stick memory), or an SD card. After selecting files and folders, open the menu with "Space-m (dots 1-3-4)", and choose the "Send To" option. When you press "Enter" on "Send To", the Braille Sense U2 displays the list of drives that you can send your files or folders to. You can choose a destination drive by using the up and down arrow keys ("Space-1" or "Space-4") or up and down scroll buttons. Pressing "Enter" on the desired drive starts the copying of the selected files and folders to the selected drive. You can activate the "Send To" option by pressing "Enter-s (dots 2-3-4)" from the file list. 

4.2.5 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. Open the menu, and choose "Copy" from the list to copy the selected files and folders. You can execute the "Copy" command directly from the file list by pressing "Enter-c". If you want to move the selected files and folders, choose "Cut" from the menu. Use "Enter-x" to execute the "Cut" command directly from the file list. When the "Copy" or "Cut" command is executed, the Braille Sense U2 returns to the file list.
3. Navigate to the destination folder.
4. Open the menu, and choose "Paste". Press "Enter" on "Paste," and your selected files and folders are copied or moved. You can press "Enter-v" to execute the "paste" command directly from the file list. 
If the destination folder is the same as the source folder, the Braille Sense U2 attaches "Copy1" to your original file names. If the same files are copied into the same folder a second time, the Braille Sense U2 attaches "Copy2" to the original file names. 
If your destination folder has the same name as the file you are copying, the Braille Sense 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.

4.2.6 Delete Files or Folders

To delete files or folders, navigate to the folders or files you want to delete, and select them. Open the menu by pressing "Space-m (dots 1-3-4)" and choose the "Delete" option. Press "Enter" on "Delete" to complete the deletion of the selected files and folders. You can also press the letter "d (dots 1-4-5)" after opening the menu to delete the selected items. You can also delete selected files or folders by using hot keys. "Space-d (dots 1-4-5)" and "Enter-d (dots 1-4-5)" can both be used to execute "Delete". 
Note: "Space-d (dots 1-4-5)" can be used with in other programs on the Braille Sense U2. "Enter-d (dots 1-4-5)" can only be used in the "File Manager". 
When you delete only one file or one folder, it is not necessary to use the select function. Instead, simply navigate to the file or folder you want to delete, and use one of the methods previously described to delete the file or folder.

4.2.7 Rename

You can change the name of a file or folder by using this function. To change the name of a file or folder, move to the file or folder you wish to rename. Open the menu by using "Space-m (dots 1-3-4)" choose "Rename" from the menu list and press "Enter", or press "r (dots 1-2-3-5)" to activate the "Rename" function quickly. You can also use the hot key "Enter-r" to activate the "Rename" function directly from the file list. The Braille Sense 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 in ASCII characters. 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: "|, \, <, >, ?, :, *"

4.2.8 New Document

Use this option to create a new document. There are several ways to access this function. You can open the menu by pressing "Space-m (dots 1-3-4)", navigate to "New Document" and press "Enter". Or, you can open the menu and press "n (dots 1-3-4-5)". The hot key for this option in the "File Manager" is "Enter-n (dots 1-3-4-5)". 
When the new document function is activated, the Braille Sense U2 displays "File type: text (txt)". You can create two types of documents: text files and Braille files. You can use the down arrow ("Space-4") to select the "Braille (brl)" file format. When you press "Enter" on either "text (txt)" or "Braille (brl)," the Braille Sense U2 displays "New document name: New Document0.txt" or "New Documen0.brl". "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.

Press "Enter" on "New Folder" to activate this function. You can use the letter "f (dots 1-2-4)" to jump the new folder option in the menu. "Enter-f (dots 1-2-4)" is the hot key that you use to access this feature directly from the file list.
The Braille Sense U2 prompts, "New folder name:,". Enter your preferred new folder name in ASCII, and press "Enter". Your new folder is created.  
When creating a new folder name, you cannot use the following characters: "|, \, <, >, ?, :, *"

4.2.10 File Conversion

The "File conversion" function on the Braille Sense U2 is similar to the "Save As" function in the Word Processor. This feature converts files to different file formats. The Braille Sense U2 file conversion feature supports the following file formats: "Sense Word (hbl)," "Text (txt)," and "Braille (brl)".
The Braille Sense U2 can convert a single file or multiple files at once to your preferred file format. Select files using the file selection method described previously. After selecting the files you want to convert, open the menu by pressing "Space-m (dots 1-3-4)". Navigate to the "File Conversion" option, and press "Enter". You can also use the letter "t (dots 2-3-4-5)" to jump to the file conversion option from within the menu. Use "Enter-t (dots 2-3-4-5)" to execute the "File Conversion" command directly from the file list.  
The Braille Sense U2 prompts you to choose the preferred file format. Use the up and down arrows ("Space-1" or "Space-4") to select the desired file format. When you press "Enter" on the file format you want, the Braille Sense U2 begins converting files to the file format you have chosen. The Braille Sense 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.

You can also activate this function directly from the file list by pressing "Backspace-S (dots-2-3-4)" when placed on the folder you want to share. 
The Braille Sense prompts, "Folded successfully shared, please reset your Braille Sense". 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 "Backspace-U (dots-1-3-6)". 
4.2.20 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 open the menu with "Space-m (dots 1-3-4)" or "F2," and press "Enter" on "Local Security Setting" Or, press "y (dots 1-3-4-5-6)" from within the menu. You can also activate this function directly from the file list by pressing "Backspace-P (dots-1-2-3-4)" when placed on the folder you want to secure. 
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 (F3 or Space-4-5)" or "Shift-Tab "Space-F3 or Space-1-2)". 
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 "Space-E (dots-1-5)" or "Space-Z (dots-1-3-5-6)". 


4.2.21 EML Viewer

The Braille Sense U2 allows you to view and interact with EML files (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 (F3 or Space-4-5)" or "Shift-Tab (Space-F3 or Space-1-2)". 

From within the Message body, use normal file reading commands to navigate the message. (See section 4, 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 "Enter-f (dots-1-2-4)" from within the message. To reply to a message, tab to the "Reply" button and press "Enter" or press "Enter-r (dots-1-2-3-5)" 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 Braille Sense U2's "E-mail" program. (See section 8 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 "Space-z (dots1-3-5-6)".

4.3 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. 

4.3.1 Editing

When you are in a file or folder list, you can press "tab (Space-4-5)" to navigate to the address window. The Braille Sense U2 displays the current path including the current drive name, such as "flashdisk/download/". When you edit the path, use the cursor routing keys to move the cursor to the place where you wish to modify the text of the path. When you first enter the address window, the cursor is located at the end of the path name. 
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.

4.3.2 Typing a Path / File Name

When you relocate the cursor with a cursor routing key, the Braille Sense 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 Braille Sense 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 Braille Sense U2 loads the Word Processor, and opens the file "sample.txt". When the file is open, you can read or edit the file, "sample.txt".

4.3.3 Opening the History List

The history list contains paths, folders, and files that you have opened previously. You can access the history list from within the address window by pressing the down arrow ("Space-4"). Use the up and down arrows ("Space-1" or "Space-4") to review the history list. You can also use the scroll buttons to navigate this list. To open a file in the history list, press "Enter". The file opens with the appropriate application. (See section 4.2.3). 
While navigating the history list, you may type in new path names or file names to instantly access a file or folder.

4.4 Network and sharing 

The network file sharing function enables you to share files between your Braille Sense U2 and computers connected to the same network, and access files on other computers just as you would files located directly on your Braille Sense U2.  
In other words, 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 Braille Sense U2.  In addition, you can share folders on your Braille Sense 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 Braille Sense 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 Braille Sense 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. 

4.4.1 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 to the network list, this list is empty. To add items to the network list, you must search the network for devices, then select the shared folders on these devices and add them to the network list. 
To search shared computers connected to the network, Use the "Network Connection Setting" dialog to search for computers with shared content. You can open the "Setup Network connection" dialog box, by pressing "Backspace-e (dots 1-5)" regardless of your position in the File Manager. Or Press "Space-m (dots 1-3-4)" or "F2" to open the menu and navigate to "Network Connection Setting" and press "Enter". 
The "Network Connection Setting" dialog box contains the following controls:

"Remote name" computer edit box 
"Remote folder" list box 
"Add/Remove" button
"Cancel" button

When the "Network connection Setting" dialog box is opened using "Backspace-e (dots 1-5)", you are placed on the "Computer name" edit box. Type the computer name with or without backslashes and press "Enter".
For example, if the computer name you want to search is "hims", type "\\hims" or "hims" 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 Braille Sense 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.

Use the following keystrokes to navigate the "Network Connection Setting" dialog:
Move to the next control: "Tab (F2 or Space-dots-4-5)"
Move to the previous control: "Shift-Tab (Space-F2 or Space-dots-1-2)"
 
Use the following keystrokes in the Remote Folder list.  
Move to the next item in the list: "Space-dot-4"
Move to the previous item in the list: "Space-dot-1"
Select current item: Space
Select all items: Enter-a (dots 1)

Use the "Add" button, to add the selected shared folder from the Remote Folder list to the File Manager's network list. From the Remote Folder list, press "enter" to exit the "Network connection Setting" dialog box. YOU can also cancel using "Space-z (dots 1-3-5-6)" or "Space-e (dots 1-5)". 
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. 

4.4.2 Remove Remote folder 

There are 2 ways to remove a remote folder from the File Manager's network list: using the "Remove" option in the network list, or via the "Network Connection Setting" dialog.
  
Using the network list:
Execute the File Manager and choose "network" from the drive list. Navigate to the remote folder you want to remove and press "Backspace-d (dots 1-4-5)". 
You can also access this function using the menu. Press "Space-m (dots 1-3-4)" or "F2" to open the menu. Arrow down to "Remove this remote folder on network" and press "Enter". 

Using the "network connection setting" dialog:
Press "Backspace-e" to open the "network connection setting" dialog. Navigate to the remote folder you want to remove. Press "tab" to navigate to the "Remove" button and press "Enter".
