    It's been a while, but I remember installing 7zip on my machine and it automatically added the option of creating a 7zip formated archive with the "Create Archive" feature that's built into Nautilus. You'd just right-click on whatever you wanna to archive, Create Archive, and then hit the drop-down box to select from a list of formats.

    He's saying the gui is missing some of the more advanced options. Like forinstance changing the compression algorithm (not the same as format).

    To answer diablo's question: the -v{partsize} command wil split your 7z archive in chunks of the size you specified.

    I took a better look at "file-roller", ubuntu's default file archiver you're referring to. The commandline options of the various formats seem to be hardcoded, however by using gconf-editor and browsing to /apps/file-roller you could change a few options. (some of the more interesting options like 'encrypt_header' and 'compression_level' are available there)

    To me the compression_level option being available in gconf but not in the create archive dialog seems like a bug. I'll check if it's already filed, and if not i'll do it after tea.

    someone already filed it:
