I'm still trying to find a compression algorithm that beats whatever 7-zip uses. The results are by magnitudes smaller than any other compression algorithm I have seen. The important thing for TZipFile component is that the archive format must compresses every file separately. Otherwise you can't extract a specific file without unpacking everything first. The other thing is the algorithms need to be free and supporting Unicode. 7-zip's LZMA does pass both requirements. I'm just not sure if it compresses filed separately - I would imagine it can/does.
