DirX-Directory of eXecutables, Version 1.08 01-Jan-92
Files compressed with AXE, DIET, EXEPACK, ICE, LEXEM, LZEXE, PKLITE,
SCRNCH, SHRINK & TINYPROG are displayed in the left window. Uncompressed
COM/EXE files are displayed in the right window. Compress and uncompress
individual and groups of files from within the program. Navigate between
drives/directories by pointing and shooting. New: Extends recognition of
files compressed with LZEXE (hacked headers) and DIET (additional headers).

Purpose:
========
To provide a simple means of easily showing which files have and have not
been compressed with an executable file compressor. It allows for easy
compression and uncompression of individual and groups of files by
user-selectable compression/uncompression programs.
DirX is a free program.
Displayed data:
===============
When the program is started, two windows pop up displaying any compressed
files and/or directories on the left and any non-compressed files on the
right. The window on the left is slightly wider to allow an abbreviated
three-character identifier to precede each filename - currently "axe",
"die", "epk", "ice", "lex", "lze", "pkl", "scr", "shr" or "tny" for files
compressed with AXE, DIET, EXEPACK, ICE, LEXEM, LZEXE, PKLITE, SCRNCH,
SHRINK or TINYPROG, respectively.
In addition to the file name, and type in the compressed window, the
default display also shows the file size, date and time for each file.
Using the "Toggle" command, the current window can be set to show any
special characteristics ("Special"), file attributes ("Attr"), the probable
correct extension for the file name if it has been misnamed ("Mis") and
which version of the compressor was used in the case of DIET, LZEXE, PKLITE
and TINYPROG files.
Please note that as DIET, at least up until version 1.10, does not
explicitly store the version number, any version number greater than 1.00
can only be interpreted in the "greater than or equal to" sense. Thus a
reading of "1.01" means that a version of DIET equal to 1.01, or higher,
was used to compress a file.
Files compressed with PKLITE Professional's extra-compression option have
an 'e' appended to the version number.
Special characteristics displayed using the Toggle command are as follows:
For the Compressed window, "dat" for "data" files (non-executables)
compressed with DIET. For the Uncompressed window, "ovl" for possible
executables containing overlays, "win" for Windows/OS2 executables and
"lhi" for LoadHi executables.
The program attempts to sense the type of display used and adjust color
appropriately. However, if the user has a color graphics card, but no
color monitor, the display may be improved by using the DOS command "MODE
BW80". Conversely, if you do have a color monitor, but the program
displays in "black and white", try using "MODE CO80".
Alternatively, two switches are available from the command line to force
black-and-white and color modes. See "Switches" below.
EGA/43- and VGA/50-line modes are supported. At program startup, an
attempt is made to detect the actual number of lines on the screen, up to a
maximum of 50, and to adjust the display accordingly.
Syntax:
=======
Usage: DIRX [switches] [d:][path][filespec] [switches]
In the above syntax, if no argument follows the program name, the current
default directory is searched, which is equivalent to "DIRX *.*". If no
file extension is specified, all extensions are searched.
Switches:
=========
-a: display Alternate info for both windows on startup. Simpler than
selecting each window in turn from within the program and using
the Toggle command twice.
-b: force Black-and-white mode. Provided as an alternative to using
DOS's "MODE BW80" command.
-c: force Color mode. Provided as an alternatative to using DOS's
"MODE CO80" command.
Either '/' or '-' may be used to specify switches.
Entering an invalid switch causes the program display a brief help screen
then exit.
Examples:
DIRX /h
DIRX -?
Configuration:
==============
The user may create or edit a file named DIRX.CFG using an editor or word
processor which can save pure ASCII text files. DIRX.CFG should reside on
the PATH, or in the current directory, when DirX is run.
In searching your path for DIRX.CFG, only the first 127 characters of the
PATH statement are significant. For "extended" paths (PATH statements
longer than 127 characters), please make sure that the path containing
DIRX.CFG is completely specified before the 127-character limit has been
reached.
The contents of DIRX.CFG allow the user to specify which program will be
invoked for compressing uncompressed files and which program(s) to use for
uncompressing the related types of compressed files (axe, die, epk, ice,
lex, lze, pkl, scr, shr, tny). Although the syntax of DIRX.CFG allows for
uncompression programs for any of the supported formats, the related
uncompressing program for a particular type may not exist at the present
time.
The syntax for specifying the *single* compression program is:
/C="prognam {filespec | options}"
Where: "prognam" is the name of the program to execute
"filespec" are format specifiers passed to "prognam" as filenames
"options" are usually switches passed to "prognam"
"filespec" may be created by a concatenation of the "%f" and "%e" format
specifiers.
If "filename.ext" is a target file, then %f represents the "filename"
portion of the complete filename, and %e represents the ".ext" part.
If no format specifiers are detected, then the current target filename is
simply appended to the end of the "prognam ... " string. This is for
compatibility with DIRX.CFG files created for use with versions of DirX
prior to 1.05.
Specific examples follow:
/C="PKLITE %f%e"
/C="AXE %f%e -n"
/C="EXEPACK %f%e %f.EPK"
/C="DIET" <- older syntax, but still works
If DIRX.CFG contains more than one line with the correct syntax for
specifying the compression program, the last one encountered before end of
file will be used.
The default command for specifying the method of compression may be
temporarily overridden from within the program. More about this later in
the "Commands" section.
The syntax for specifying the uncompression program(s) is:
/U<xxx>="prognam {filespec | options}"
Where <xxx> is "axe", "die", "epk", "ice", "lex", "lze", "pkl", "scr",
"shr" or "tny" for files compressed with AXE, DIET, EXEPACK, ICE, LEXEM,
LZEXE, PKLITE, SCRNCH, SHRINK or TINYPROG, respectively.
"prognam", "filespec" and "options" have the same meanings as discussed
above for specifying the compress command.
Specific examples follow:
/Upkl="PKLITE %f%e -x"
/Udie="DIET -ra %f%e"
/Uepk="UPACKEXE %f%e"
If DIRX.CFG contains more than one line with the correct syntax for
specifying the uncompression program for the related type of compressed
file, the last one encountered before end of file will be used.
In the above syntax for DIRX.CFG, neither leading and trailing spaces, nor
any other extraneous characters are allowed. Lines with invalid syntax,
including invalid format specifiers, are simply ignored. This may actually
be used to advantage, as shown in the *sample* DIRX.CFG file, where the
single quote character is used to "comment-out" some of the non-applicable
lines, but where the user may want to retain these lines to save retyping
should he/she want to later change which is the default compression
program, for example.
The sample DIRX.CFG file is included in the distribution archive, which the
user may edit to "customize" DirX's behavior.
Commands:
=========
The current or active window is the one with the solid frame. Within the
active window, <Home>, <End>, <PgUp>, <PgDn>, <UpArrow> and <DownArrow> may
be used to navigate. The <Tab> and right/left arrow keys will toggle the
active window between the left and right panels.
If any directories are displayed in the left (Compressed) window, moving
the file selection bar (highlight) over that directory and pressing
<Return> will change the directory being viewed. The file lists will be
updated automatically.
Two shortcut keys are available for navigating directories while in the
Compressed window:
"Ctrl \" changes the current directory to the root directory - similar to
"CD \" at the DOS level.
"Ctrl <PgUp>" changes the current directory to the parent directory -
similar to "CD .." from DOS.
To change the current default drive from within the program, use either
"Alt <F1>" or "Alt <F2>". A window indicating valid drives will pop up,
allowing the user to select another drive by moving the highlight with the
left and right arrow keys, then pressing <Return> to select the new drive.
As an alternative, you may also type the letter of the drive. Press <Esc>
to leave the default drive unchanged. The drive changing feature is only
valid when using versions of DOS numbered 3.0 or higher.
Pressing <F1> or the letter 'H' will display a brief help screen
summarizing commonly used commands. Press any key to close the help
window.
Pressing <F3> or the letter 'D' will turn Directories-only mode on. To
turn Directories-only mode off, press <F3> or 'D' a second time. (This
feature was added by user request to speed up navigation on a relatively
slow machine.)
Pressing <F4> or the letter 'T' will toggle the active window's display to
show additional information on the files being displayed, as previously
described in the "Displayed data" section above.
Pressing <F6> or the letter 'M' when no files have been selected will cause
the Move command to act on the currently highlighted file. If any files
have been selected, the Move command acts on the selected files.
If the Move command is given while in the "Compressed" window, the DOS
command "<uncompPrognam> <filename>" is executed for each selected file,
where <uncompPrognam> is the name of the uncompression program and
<filename> is the name of the file to uncompress.
If the Move command is given while in the "Uncompressed" window, the DOS
command "<compPrognam> <filename>" is executed for each selected file,
where <compPrognam> is the name of the compression program and <filename>
is the name of the file to compress.
Pressing "Alt <F6>" or "Alt M" from either the Compressed or Uncompressed
window will open an input window which will allow the user to temporarily
"Alter", or override, the method of compression currently defined in
DIRX.CFG, on the fly, from within DirX.
For compressing/uncompressing to work, the commands <compPrognam> and/or
<uncompPrognam> should either be available in a directory included in the
PATH environment variable, or in the current directory. Tip: Either of
these "programs" may be batch files.
Files may be selected, or tagged, either individually or by wildcard
selection. The <Ins> key may be used as a toggle to select and unselect
individual files. Pressing <Ins> on an unselected file selects it.
Pressing <Ins> on a selected file unselects it. To select a group of files
using DOS-type wildcards, press the plus ('+') key. This opens up an input
window into which a file specification may be entered. To unselect a group
of files, press the minus ('-'). This opens up an input window similar to
the one for selection. The suggested keys are the gray plus and minus keys
found near the numeric keypad of many keyboards.
Pressing <F7> or the letter 'S' will open an input window for the user to
enter a file specification to search for within the current window. If
wildcards are used, and the Search command is repeatedly invoked without
changing the search specification, the program will cycle through all
matching file names.
Pressing <F9> or the letter 'P' or '/' will invoke the pull-down menu
system.
Pressing <Esc>, <F10> or the letter 'Q' will exit the program.
Pull-down menus:
================
The pull-down menu system duplicates in functionality many of the commands
already described in the Commands section. The purpose of this menu system
is to de-emphasize the use of function keys and cryptic Alt- and Ctrl-key
sequences when adding new commands in the future.
The Move command, invoked by function key, is replaced by two separate
commands in the pull-down menu system. These are the "Compress" and
"Uncompress" commands, listed under the "File" submenu.
For the Uncompress command to work, the Compressed window must be the
current one. This command is equivalent to using the Move command while in
the Compressed window.
The Compress command, depending on which window is active, can act on files
in *either* the Compressed or Uncompressed windows. The purpose of
allowing the user to *attempt to* compress already compressed files
(something that is available from the command line anyway) is to facilitate
experimentation on the effects of compression by a variety of methods -
compressing files already compressed with EXEPACK, for example.
