- I am not sure if there is a program on the mac that can uncompress .Z files,

- able to use "uncompress" to uncompress those files.

- Stuffit does not decompress Compact Pro. I do not know if Compact Pro
- decompresses Stuffit files.

- BinHex converts a binary file to a text file. It seems that many programs
- can only handle text files. Programs like elm, trn, etc do not like binary
- files. So BinHex converts the binary file to an ASCII file. The reason it
- is bigger is (I could be wrong) that binary files use the full 8 bits whereas
- ASCII only uses 7 out of the 8 bits. So more bytes are needed to represent
- the file.

- On unix systems, .tar files are tape archive files. You can use the tar
- program untar the files. Sometimes a large group of files will be tar
- together, but most compression programs for the mac do a better job of
- compressing groups of files, so I doubt you will see mac files tarred.
