DC Xtract 2.1
-------------
Program written by Paul W. Lee
(C) Copyright 1990 Double Click Software
DC Xtract revolutionizes the method used to manipulate your archive files.
No longer will you need to remember dozens of command line options or be
forced to use shell programs. DC Xtract handles in one program, the
equivalent of four different compression-archival programs, with a user
interface unmatched by any other archival system.
DC Xtract uses a GEM window to show the files within a archive. Then you
can select on the file and perform various functions with it.
------------------
Window Information
------------------
DC Xtract shows the file information in the following format:
YMODEM.DOC 66489 Crunch 58% 28538 10/27/87 10:00a C291

Note: ZIP uses a 32 bit CRC, because of the limited space within the
GEM window, DC Xtract shows only the lower 16 bits.
---------------
Selecting Files
---------------
You can select a single file by pointing the mouse to it and clicking on the
left button. Selecting multiple files may be done by using the rubber box.
Note: Pressing on the LEFT shift and using the rubber box will also select
files within a sub-directory.

Main Dialog Buttons
-------------------
CONFIG
------
After clicking on the 'CONFIG' button, you will be presented with the
'DC Xtract Configuration Menu'. There are 11 options which you may adjust:
Archive Format : ARC,LZH,ZIP,ZOO,AUTO
----------------
This allows you to select between four archive file formats :
ARC,LZH,ZIP,ZOO and AUTO. You may use the following keys to
switch formats from the main dialog. In AUTO mode, DC Xtract
will use the file extender to select the mode.
F1 = ARC, F2 = LZH, F3 = ZIP, F4 = ZOO, F5 = AUTO
Overwrite existing files : NO or YES
--------------------------
With this option set to 'NO' and a file with the exact name is
found, a prompt will appear asking you if you want to overwrite
existing file, skip, or quit. If this option is set to 'YES', no
prompt will appear.
Create directories : NO or YES
--------------------
If this option is set to 'NO', all files will be extracted to the
path you have seleted. With this option set to 'YES', directories
will be created starting with the path you have selected.
Add directories : NO or YES
-----------------
If this option is set to 'NO', only files in the current directory
will be added to the archieve. With this option set to 'YES', all
files in the current directory and subsequent subdirectories.
Show directories : NO or YES
------------------
Setting this option to 'YES' will show files which are archived
within archived to be shown. Otherwise, the file is shown as one
archive file.
For example, if a ARC file is contained within another ARC file,
and this option set to 'YES', you can see the files of the second
ARC file.
Maintain file Date/Time : NO or YES
-------------------------
Setting this option to 'YES' will use the date and time given in
the archive header of each file, instead of the current system date
and time. Using 'NO' will use the current system date and time.
Abort on bad header : NO or YES
---------------------
Setting this option to 'YES', DC Xtract will abort reading the
archive headers if a bad header is encountered. However, there may
be times which you may want this set to 'NO', to recover files
in a corrupted archive file. Note: Recovering bad headers may take
long periods of time, if you feel too much time has elapsed, press
the ESC key to abort.
Auto select all : NO or YES
-----------------
If this option is set to 'YES', then all files will be selected
when the archive is first opened.
Source Path : SAVED or CURRENT
-------------
If this option is set to 'SAVED', the source path for archives
will be the user defined path. Otherwise, the current path
will be used.
Destination Path : SAVED or CURRENT
------------------
If this option is set to 'SAVED', the destination path for
extracting files will be the user defined path. Otherwise, the
current path will be used.

extenders, however, if none of the pre-defined extenders suits
your needs, you may choose a user definable extender.
Note : The is no wildcard matching on extenders. If you have a need
to use wildcard searching use 'MASK 1' or 'MASK 2'.
Files to search : Current or All
-----------------

selected. For example, if you are on the root level of the archive
file, only those files are searched. Other files which are
