    I've got large, uncompressed video files (400gb) that I'd like to archive and split into smaller chunks and save offsite. I'm looking for an app or zip syntax that would allow me to take a monolithic file and archive it (zip/arj/rar etc) into chunks of, say, 4gb - and then at a later date be able to rebuild the parts into a larger file.

    WinRAR on Win32 does exactly this - but I'm on OS X 10.5, so it's not an option. I can't use zip then zipsplit as the output file is too large and zip bombs out (gracefully). Any suggestions greatly appreciated, this is beginning to drive me bonkers.

    The UNIX commands split and join will do what you require.

    I guess you might want to do something similar to this:
    split -b 4000 m myvideo.avi.bz2 myvideo.avi.bz2.
    Then to join the files:
    cat `ls -1 myvideo.bz2.*` > myvideo.bz2
    Or you could download the command line version of Rar for the Mac and use that.

    Ah, bzip, of course! Thanks very much, stomer!

    Edit: ha, you removed the reference to bzip, so now I sound crazy ;)
