Correct me if I am wrong but doesn't the .Z extension o. The file name indicate that the file is compressed? If so you just need to run the files through the compress program.

Yes, I think leader716 is right!
Files with extension ".Z" are compressed.
Check if your files are already compressed and just have the wrong (or no) extension with e.g.
file test1
If you see e.g. "test1: compressed data block compressed 16 bit" the files are actually compressed and you should follow point_pleasant's suggestion.
If you don't see the above then compress the files with
for file in $(ls -1 test*); do compress $file; done
The files will get the ".Z" extension automatically.
The above one-liner just feeds the names of all files starting with "test" into the compress program, one by one (thus the "for" loop).
Please note that it's the digit "1", not the letter "l" in "ls -1".

Faster:
compress test*
compress test*
do
mv $i $i.z
done
