- Files v0.08, display open files table under Desqview
- Portions Copyright (C) 1991, W.H. Bond
-
-
- This started out as a quick & dirty program for my own use. After playing
- with it a little and with some prodding (ouch :-)) by Don Dawson of
- 1:141/730, we thought it was too fun not to pass along.
-
- This program is based on a Byte Magazine article (March 1991)
- _Undocumented_DOS_ by Andrew Schulman, the article was adapted from the
- book of the same name, by Andrew Schulman, Raymond J. Michels, Jim Kyle,
- Tim Paterson, David Maxey, and Ralf Brown.
-
- Written using DVGLUE by Ralf Brown & Ralf Brown's INTER191.Zip. Thanks
- Ralf.

- no warranty expressed or implied. The user of this program assumes all
- responsibility for the operation of, and any consequences of using, this
- program.
-
- Files displays a table of currently open files. It will loop continuously
- until the ESC is key pressed. It will only run under Desqview and DOS 3.1
- or higher (I've only tested it with DV 2.31 and MS-DOS 3.3 with Share.exe
- loaded).
-
-
- Fields displayed:
- y/n sleep mode on (+) or off (-)
- Filename Ext name/ext of file
- Size current file size
- Offset current offset into file
- Attr files' attribute
- Mode open mode
- Date files' date
- Time files' time
- Hnd # of file handles referring to this file(?)
- PSP File owners PSP
-
-
- Active Keys:
- Esc Exit/Quit
- PgUp/PgDn Moves between display screens (if more than one)
- Home clear and redraw screen
- F1 Open help window
- F2 Toggle open/all mode
- F3 Toggle regular/open mode display
- F4 Toggle sleep/nosleep mode

- F1 will open a small help window, press Esc to close it. The DVP file
- enclosed provides 2k of system memory needed to pop up the help screen.
-
- F2 or the space bar will toggle open/all modes. The initial mode shows
- only open files. The all mode will dump the whole file table, files that
- are not open will show a 0 in the 'handles' column.
-
- F3 will provide more detail about the open files, sharing modes and file
- attributes.
-
- F4 toggles sleep mode on and off. When sleep mode is on the program will
- give up one second of time after each screen refresh, this is the default.
- This allows Files to use very little overhead. While sleep mode is on a
- '+' will be displayed in the upper left hand corner of the screen. When
- sleep mode is toggled off the screen redraw will be more frequent, at the
- expense of hogging more system time. The '+' will change to a '-' when
- sleep mode is toggled off.
-
- F5 toggles display of the full path to the open files if share.exe is
- loaded and the file is found in the Dos sharing table.
-
- F6 toggles display of closed file info if the all mode (F2). This enables
- you to view the entire files table but suppresses display of info for
- unused or closed entries. It may be easier to use this mode if many files
- are opened and closed quickly, since the positions of the open files won't
- jump around on the screen.
-
-
- Files attempts to be smart about the screen length and displays only as
- many files as will fit on the screen. If you resize the window it will try
- to adjust to the new window height. Pressing the Home key will allow you
- to reset the display manually if it becomes confused.
-
- The DVP file included provides Files with 18k of memory. If Files doesn't
- run properly on your system then adding a small amount of memory may help.
- The DVP also provides 2k of system memory for the help screen.

- Revision history:
-
- files005 6/25/91 Added full path display (F5).
-
- files006 9/10/91 Added help window (F1). Fixed problem with
- FCB display occasionally causing window to
- scroll.
-
- files007 9/27/91 Added F6 key option. Added version number to
- help screen. Fixed FCB display under Dos
- v5.0. It appears that Dos 5.0 doesn't zero
- out the FCB table, so garbage would be
- displayed for unused FCB entries.
-
- files008 10/2/91 Fixed a couple of minor nits in the FCB display code.
- It was still displaying garbage in certain
- circumstances.
