It is also possible to attach disk or tape images that have been compressed through various algorithms; compression formats are identified from the file extension. The following formats are supported (the expected file name extension is in parenthesis):
.gz
or .z
);
.bz2
);
.zip
);
.tar.gz
, .tgz
);
.zoo
).
PkZip, tar.gz
, lha
and zoo
support is
read-only and always uses the first T64
or
D64
file in the archive. So archives containing multiple files
will always be handled as if they contain only a single file.
Windows and DOS don’t contain the needful programs to handle compressed archives. Get gzip and unzip for Windows and for DOS at http://infozip.sourceforge.net. Don’t use pkunzip for DOS, it doesn’t work. The programs to use BZip2 archives may be found at https://sourceware.org/bzip2/. Just put the programs (unzip.exe, gzip.exe, bzip2.exe) into a directory of your search path (e.g. C:\DOS or C:\WINDOWS\COMMAND; have a look at the PATH variable).
