Acadia,

On Windows I Like WinRar as well, it supports file sizes up to 8 gigs (on NTFS), and has a pretty good command line interface. 

So if you have to manage lots of files and gigs of disk then WinRar is probably your best bet.

If your on mac they do have the command line rar utility that you can also use.
