220.127.116.11 Decompressing Zipped Files
All ACATS files have been compressed (zipped) into
compressed archives (zip-files) that have the MS-DOS file extension ".zip".
A Windows command-line utility was used to compress them. They must be
decompressed before they can be further processed. A decompression utility
is available from the source of the ACATS distribution. All ACATS 4.1
files may be decompressed using the following steps. Approximately 48
MB of free space on a Windows machine hard drive will be required to
accomplish the decompression using this technique.
Create a directory on the hard disk to contain ACATS.
In these examples, we assume the name is acats4_1, but any name
can be used. Copy the archive (file with .zip extension) to the hard
disk in the new directory. Decompress it insuring that directories are
used. For the unzip program, this is the default setting. For
the pkunzip program, this is the -d option. For the winzip
program, ensure that "Use Directory Names" is checked. Also,
ensure that the files are decompressed into the proper directory. For
command line decompressors, this means ensuring that the current subdirectory
is acats4_1. For winzip, this simply means selecting acats4_1
as the extract path.
For example, using
unzip, and assuming that the archive name is ACATS41.zip, type
to set the proper directory,
to extract the files.
The files were compressed on a Windows system, where
<CR><LF> is used as a line terminator. Decompressors for
other systems using other line terminators should be able convert the
line terminators. The ACAA has a short Ada program which converts a file
from Windows to Unix format; please send the ACAA mail at firstname.lastname@example.org
to request it if needed.
After all files have been extracted from the archive,
delete the archive file from the hard disk if you wish to conserve space.
As it decompresses files, unzip will restore
the directory structure of the files, creating all needed subdirectories.
Some users may prefer to work with ACATS files in
an alternate directory structure or none at all. If the unzip
utility is invoked with the "-j" option, all files in the archive
will be decompressed and placed in the local working directory. In other
words, none of the above subdirectories will be created. Since there
are too many ACATS files to fit into a root DOS directory, if you wish
to put all files in a single directory, you must first create a subdirectory
(e.g., mkdir \ACATS) and unzip all archives there.
