I want to compress a 16GB folder, but what's the best method? tar.gz? tar.bz2 rar? 7z? Would the archive be smaller if I first compressed in a method, then copy the compressed archive to a new folder, then re-compressed in some other method? I need to make it fit on a DVD (output maybe 8.5GB, don't remember) but putting "4370 MB" makes the compressed file be 2.5GB part.



BTW, what's the default compression method on Ubuntu?

The default is gz. The best results I get with 7z though.
