A long time ago, in a galaxy far far away........
.CYM meant that the file was compressed with the program CRLZH.COM
you can uncompress it with UNCRLZH.COM
Joe was quite right. There were all sorts of compression algorithms at
the time, squeezed, arked, arced, self-extracting arc, and yada
yada. The authors of each claimed various advantages, such as more
efficient compression, or smaller size, and the like.
If was all for use back in the time when sending files online with
dialup equipment at 300 baud was expensive, so the fewer kilobytes
you had to send, the cheaper it was. Everything got compressed prior
to sending, which meant that it had to be uncompressed at the other
end. When it came to compression/decompression software there were
quite a few "flavours of the month". These days we've abandoned all of
that in favour of ZIPS or GUNZIPS or BZ's,TARs,TARBALLS and
BZEDDEDTARBALLS - or is it .TAR.BZ --- something like that.
Some things never change.
