AUTO UNPACK
Version 1.02
A Cando Application By
Carlos J. Velazquez
March 6, 1992
==========================================================================
SYNOPSIS: Auto Unpack is a Cando v1.5 deck that will automatically
decompress archived files from a source directory to a given destination
directory. It will decompress each file into a unique temporary directory
in RAM:. It then checks the size of the new, uncompressed directory and
determines whether it will fit in the destination directory. If so, it will
COPY the entire directory to the designated destination and then will erase
both the temporary directory in RAM: and the archived file in your source
directory!! It will only do these last two steps if the decompressed
directory was successfully copied to your destination directory.
CONTENTS: The following files are part of Auto Unpack:
AutoUnpack - Main Deck
AutoUnpack.doc - This file
AutoUnpack.info - Icon
AutoUnpack.doc.info - Icon
AUTitle.iff - Main panel picture
AUBlank.iff - Secondary panel picture
INSTALLATION: You may copy all of the above files into any subdirectory or
root directory on a disk or hard drive. All the files MUST reside in the
same directory! You must have the following AmigaDOS commands available (in
your 'C' Directory): COPY, ASSIGN, DELETE, and MAKEDIR. Additionally you
must have DECKBROWSER (freely distributable from Inovatronics) in your c:
directory. Deckbrowser is available from many fine area bulletin boards.
ADDITIONAL REQUIREMENTS: The following archive utilities are used by Auto
Unpack and are not included in the distribution packet: ARC, LHA, LZ,
UNZIP, & ZOO. Auto Unpack was tested with the following versions of the
above software: ARC (AmigArc V.16), LHA V1.0, LZ V1.92, UNZIP V3.10, and
ZOO V2.0. PLEASE NOTE: These archive utilities MUST be in your c: directory!
USAGE: Double-click on the icon. This will launch the deck and you will see
string gadgets for both Source and Destination directories. These can be
either device names (DH0: DF0: etc) ending in a colon or a DIRECTORY (not
ending in a slash (/). It must not be an existing file! AUTO UNPACK will
not prohibit you from entering a filename but the program will not function
properly. It will check to make sure your entries actually exist before
letting you continue, warning you when your entry does not exist.
After entering both Source and Destination directories, click on 'GO'. This
will usher you into the processing section of the program and prompt you
for one more click. You will see the number of files to be processed and a
progress report indicating which file is currently being processed and in
which state it is (Decompressing, Moving, Etc.). Auto Unpack will process
all the files in your source directory that end in .ARC, .LHA, .LZH, .ZIP,
& .ZOO (need not be uppercase). When finished, it will display "DONE" and
will exit, quietly deleting all temporary files it used from RAM:.
BUGS: Auto Unpack runs fine on an Amiga2000 running 2.04 ROMS. Extensive
error-trapping has not been implemented yet :-{). That is, the size of your
RAM DISK: is not checked prior to decompressing; it will let you select
RAM: as a destination (which is obtuse!); AND it does not give you a
"window" on the decompression process, thus you cannot answer prompts such
as "File Exists. Overwrite (Y/N)?". These problems will be addressed in a
later version, "Coming Real Soon ...".
