You should first tar everything in one file and afterwards bzip2/gzip the single file. Unlike with Winzip, the process of archiving and compressing is separated in 2 commands. gzip/bzip/winzip are general-purpose compressors. They do quite good on average, but specialized compressors (ie they know what kind of input they get) will always be better. Sargon
