Best Method of Compression

I am using 7zip and trying to find the best method of compression to no avail, i can't seem to be able to compress it to a decent amount.

My question is, what are the best settings for compression using 7zip regardless of speed? I want to compress it for the smallest amount of disk space.

Probably your best bet, mayhaps not the fullest extent of compress but widely used and accepted is the .tgz format or .tar.gz as it more oftenly comes packaged in. Not being a compression expert at all - but I believe this is a double compression method, where the files are first zipped using a tarball .tar method, then zipped again using gzip compression.

In windows using 7zip or stuffit, to unpack these files you usually unpack that .tar.gz to a .tar, then unzip a second time to get the actual files.

-- corrections accepted, I'm just spouting off here on a topic i'm fairly unfamiliar with.

Check this out. Also this. If you are looking for a ridiculous compression ratio, KGB is your best bet. I'd like to warn you though, KGB is unstable and resource intensive. The main site is down atm but save the URL for a visit later.

I have even heard (unverified) stories of a 10:1 compression ratio. Be sure to check it out.

Have fun!
