- SECTOR? <Alone-F5>
-
- Enter new sector to view (ESC to abort) [0-xxxxxxxxxx]: _
-
- Please note that the very first sector is actually SECTOR 0 !
- The "Total Sectors:" display, at the lower left-hand corner of the screen,
- is the total 1-based sector quantity. Which is how normal people count.
- xxxxxxxxx = the maximum sector number that you can input, in decimal.
- To input the desired sector number in hexidecimal, end it with an "h".
- For example: 1111h<Enter>
-
- If you have an individual file loaded for editing, the allowable sectors
- are restricted to the sectors that belong to that file.
- (This is done via <Alone-F7> FileDir, and the file is known as the
- "Current File".) And the prompt would then be:
-
- Enter new file sector to view (ESC or ENTER alone to exit): _
-
- If there are unsaved sector changes, the procedure is the same as
- <Alone-F10> Exit DE.
-
- ----------------------------------------------------------------------------
- DRIVE? <Alone-F6>
-
- To select a new drive, either user the right and left arrow keys to
- highlight the desired drive letter and press Enter. Or Double left mouse
- click over the desired drive to view. A right mouse click equals ESC (exit)!
- Please note, if you have a CD drive installed, its drive letter will
- not be shown. Their structure and access methods (programming wise) are
- entirely different from that of a magnetic disk.
- If the requested drive exceeds the limitations of this program, you
- would see one of the messages below, and the drive change would be aborted.
-
- +-|ESC|---------------------------------+
- | Error: Sector size of requested |
- | drive exceeds 4096 bytes. |
- +---------------------------------------+
-
- +-|ESC|---------------------------------+
- | Error: Cluster size of requested |
- | drive exceeds 128 sectors. |
- +---------------------------------------+
-
- If there are unsaved sector changes, the procedure is the same as
- <Alone-F10> Exit DE.
-
- NOTE: If you select a drive and the (floppy) drive bay is empty,
- the default DOS INT 24h handler will temporarily take control of the system
- and display: Not ready reading drive x <---- A or B or whatever.
- Abort, Retry, Fail? (DOS v3.2- = Abort, Retry, Ignore?)
- The only safe route then is to press "F", "I", or insert a disk and press "R".
- ABORT will crash the program, leaving you with no command line cursor and
- a useless active mouse cursor! Page 14

- FILEDIR <Alone-F7> MENU
-
- The FileDir Menu is fairly powerful. The maximum number of files that
- can be read and displayed, in each directory, is 1191. This includes, and
- displays, 1.) Volume Labels, 2.) hidden files and directories, 3.) read only
- files and directories, 4.) system files, 5.) long filenames, and 6.) erased
- files (these begin with the E5h character).
- FYI. The first byte of a 32 byte directory entry being 00h (binary 0)
- indicates that there are no more files in that directory. NEVER do this
- yourself, or you may render any remaining files inaccessable!
- The "File: xxxx" display, at the lower left-hand corner of the screen,
- shows exactly which 32 byte directory entry that the highlighted file or
- <DIR> is, within the Root Directory sectors or the Sub-Directory cluster.
- The "LEGEND", at the right side of the FileDir Menu, is a simple help
- screen of allowable key presses. If using a mouse, a right or left click
- over any command, will execute that command.
- If the logged drive is empty of files, you would see this message:
- +-|ESC|---------------------------------+
- | There are no files to display! |
- +---------------------------------------+
- To access and load a <DIR>, either move the highlight bar to the desired
- directory filename and press Enter. Or use the mouse and double left or right
- click over the desired directory filename. The maximum number of
- sub-directory levels is 6. If an attempt is made to go any deeper, you would
- see this message:
- +-|ESC|---------------------------------+
- | !!! SORRY !!! |
- | The maximum nested level in viewing |
- | sub-directories is 6. |
- +---------------------------------------+
- To load and initialize a particular file for viewing/editing, either
- move the highlight bar to the desired file and press Enter. Or use the
- mouse and double left or right click over the desired file. The selected
- file then becomes the "Current File". To exit back to the FileDir Menu,
- press either <Shift-F10> Exit CF or <Alone-F10> Exit DE.
- a.) The maximum number of file clusters that can be read, from the FAT,
- is 16,383. This would be a minimum file size of 8,388,096 bytes
- (with 512 bytes per sector and 1 sector per cluster). As far as I
- know, this minimum could only be accomplished with a 32-bit FAT.
- If the number of file clusters DOES exceed 16,383 you would see
- this message:
- +-|ESC|---------------------------------+
- | Sorry!! Could not load all of the file|
- | clusters. This program can only handle|
- | up to 16,383 file clusters. :
- +---------------------------------------+
- You would still be able to continue, but would not be able to
- access the entire file.

- NOTE: You must use <U>nerase in order to access and view the

- is still free, it is the only cluster that can be viewed.

- NOTE: If after unerasing a file or <DIR>, you exit to DOS, and the
- directory that you are in is the same directory as the unerased file or
- <DIR>, you will need to do this:
- C:\>dir "the unerased filename.ext" <Enter>
- The reason for this, is that DOS keeps an internal memory buffer of the
- current directory. And unless DOS itself does the file handling, this
- internal buffer is not updated. Therefore, DOS will not recognize the
- newly unerased file or <DIR>! This forces DOS to update the buffer.
