Compressed File DIRectory utility
CFDir is NOT a full featured front end for your compression/decompression
utilities. It is a utility that was created to work in conjunction with
the ReadIt text file viewer (version 2.7 and later) to enable the user
to read files within a compressed file without first extracting them.
CFDIR.EXE and CFDIR.DOC are a part of the ReadIt package.
Although CFDIR was written to be used with ReadIt, it can also be used as
a "stand-alone" utility for viewing the directory of a compressed file.
You can also have CFDIR call up the appropriate de-compression utility to
extract one or more files from the compressed file.
NOTE: While CFDir does not need the help of a decompression utility to
display a list of files within a compressed file, it does call a
decompression utility to actually extract them. Those utilities which
CFDir will use are listed later in this documentation. DLJ Software does
not sell or distribute compression/decompression utilities.
We will first discuss how to use CFDir as a "stand-alone" utility. After
which, we will talk about using CFDir with ReadIt.
Running CFDir:
As with READIT.EXE and RIC.EXE, you should place CFDIR.EXE in a directory
which is in your DOS path so that it can be run from anywhere on your
system. This is also important because ReadIt must be able to find CFDir
in order to use it.
You will need to have approximately 150kB of RAM available when you run
CFDir as a "stand-alone" utility if you intend to use it to extract
selected files. NOTE: Some decompression utilities need a large amount
of RAM available in order to run. The amount of RAM mentioned above might
not be enough for some of these utilities.
The format for using CFDir from the DOS command line is:
CFDIR [drive][path][filespec] [/W-]
The square brackets ([]) simply mean that the parameter which they
enclose is optional. [drive] refers to a legal DOS drive specification
such as "A:", "B:", "C:", etc. [path] refers to a legal DOS path such as
"\" (the root directory), "\DOS" (a sub-directory of the root directory),
or "DOCUMENTS" (a sub-directory of the current directory). [filespec]
refers to a legal DOS filename and extension such as "FILES.ARC", or a
group of files specified by using the DOS wildcards "*" and/or "?" such as
"FILES.*" or "*.ARC".
[/w-] switches the picklist display from full file information ("wide"
display) to filenames and extensions only. The /W switch must either be
the last parameter or the only parameter. Anything that follows it on the
DOS command line will be ignored.
If any of the parameters above are not specified, CFDir assumes default
values. The defaults are as follows:
drive -- Current drive.
path -- Current path (directory).
filespec -- "*.*" (without the quotation marks).
/w+ -- full file info on picklist (wide display).
It should be noted that, although you can use wildcards to specify the
file extension, only files with the extensions listed below will be
considered since CFDir only works with compressed files. Valid file
extensions are:
.ARC .LZH .ZIP .ZOO .ARJ .PAK
If you run CFDir and specify a single filename, CFDir will attempt to show
you a listing of the contents of that file. If you use wildcards, or
do not specify any filespec, CFDir will attempt to show you a list of
compressed files residing on the current, or specified, drive and path.
What CFDir looks like:
CFDir appears the same as the default ReadIt with the picklist up. The
status line is displayed on the top line of the screen, and the help/error
message panel is displayed on the bottom two lines of the screen. A
picklist containing filenames, file sizes, dates and time is displayed
between these two panels.
The status panel will display either "Directory of..." or "Contents of..."
depending on what is being displayed in the picklist--either a list of
compressed files within the directory, or a listing of files within a
particular compressed file.
CFDir commands:
When CFDir is up and displaying a picklist, the following commands are
available.
ESCAPE -- Exit picklist or program.
ALT-X -- Exit directly to DOS (eXpress eXit).
F1 -- Display help screen.
UP ARROW -- Move picklist highlight bar up one entry.
DOWN ARROW -- Move picklist highlight bar down one entry.
PAGE UP or
PAGE DOWN -- Scroll picklist up or down one screen full.
HOME or
END -- Move highlight bar to beginning or end of
picklist.
ENTER -- Select highlighted entry.
As with ReadIt's picklist, you can sort the entries in CFDir's picklist.
ALT-F1 -- Sort by filename.
ALT-F2 -- Sort by file extension.
ALT-F3 -- Sort by file size.
ALT-F4 -- Sort by file date and time.
ALT-F5 -- Sort by filenames, and within filename groups,
sort by extensions.
ALT-F6 -- Sort by file extensions, and within extension
groups, sort by filenames.
ALT-F9 -- Switch between ascending and descending order.
When you first run CFDir from the DOS prompt, the picklist is displayed in
the order the files occur either in the directory or within the compressed
file. Also, the picklist will be in "wide display" mode. That means that
it will display full information about the files. You can switch between
"files and extensions only" display and "full information" display, as you
can with ReadIt's picklist, by pressing the ALT-F10 combination.
The action performed when you press the ENTER (select entry) key depends
on what is being displayed in the picklist.
If the picklist is displaying a list of files contained in a directory,
pressing the ENTER key will cause CFDir to attempt to display a list of
files within the highlighted compressed file in another picklist.
However, if a list of files within a compressed file is being displayed,
CFDir will attempt to find a decompression utility on your hard drive and
have it extract the highlighted file.
NOTE: CFDir first searches the current directory, and then searches all
directories included in the DOS path for a decompression (de-arching)
utility. If you are not familiar with DOS environment variables or the
DOS path, refer to your DOS user's manual. Below is a list of the
compression/decompression utilities that CFDir will search for:
FOR .ARC:
ARC-E.COM and
ARCE.COM -- Wayne Chin and Vernon D. Buerg
System Enhancement Associates
PKUNPAK.EXE -- PKWARE
PKXARC.COM -- PKWARE
FOR .LZH:
LHARC.EXE -- Haruyasu Yoshizaki (Yoshi)
LHA.EXE -- Haruyasu Yoshizaki (Yoshi)
FOR .ZIP:
PKUNZIP.EXE -- PKWARE
UNZIP.EXE -- BORLAND INTERNATIONAL
FOR .ZOO:
ZOO.EXE and
ZOOX.EXE -- Rahul Dhesi
FOR .ARJ:
ARJ.EXE,
ARJR.EXE and
DEARJ.EXE -- Robert K Jung.
FOR .PAK:
PAK.EXE -- NoGate Consulting
Over time, the authors of some of these utilities may have changed their
compressed file formats (".LZH" files for example). If CFDir does not
work with your compressed files please inform us at DLJ Software.
Include the utilities name and version number.
Note: DLJ Software has no vested interest in any of the above mentioned
utilities, and makes no judgements or recommendations as to their
usefulness, reliability, availability, etc.. We have simply made an
attempt to make CFDir compatible with as many decompression utilities as
is practical.
Using CFDir with ReadIt:
You will need to have approximately 250kB of RAM available before running
ReadIt in order to use ReadIt and CFDir to view text files within
compressed files. Also, as mentioned above, CFDir should be placed in a
directory where ReadIt will be able to find it. NOTE: Because some of
the supported decompression utilities require a large amount of RAM, the
250k above may not be adequate for some users.
Other than what is mentioned in the paragraph above, you need not do
anything special to use CFDir with ReadIt. It's all pretty much
automatic.
Think of a compressed file as being similar to a sub-directory, as far as
ReadIt is concerned. There are only a few differences in the picklist
when in this "sub-directory".
(1) You can not perform DOS commands using the F10 key.
(2) You can not rename or delete files in this directory.
(3) You can not use ALT-f8 to have ReadIt turn off sorting and
" reread" this directory. And,
(4) You need to press the ESCAPE key to return to the previous
directory.
That's about it! Also, although you can not change the appearance of
CFDir as a stand-alone utility, It is a bit of a chameleon when used with
ReadIt. What that means is, When used with ReadIt, CFDir will take on the
same "look".
Sharing CFDir with others:
CFDIR.EXE and CFDIR.DOC are not free. They are copyrighted and are part
of the ReadIt shareware package. Refer to the ReadIt documentation for
information on how the ReadIt package may be shared with others for
evaluation purposes.
