Theres many compressors out there...

Winrar
winzip
uharc
7-zip
Arj
freearc
lzh
ntfs file compression
etc..

Compression results entirely depend on the data and algo and dictionary size (if the algo uses a dictionary) so only you can answer your question by experimenting..i'd say winrar should do a decent job probably
