There are similar things on the Acorn that can handle arc files and tar.gz files, but it is very slow for tar.gz as the whole archive has to be read or written at any access. You could get around this by using a gz.tar file (with tar's blocksize changed to the disk's frag size), but a whole compressed FS (like Doublespace etc. for DOS) would be better than either. -- Michael Searle - searle@longacre.demon.co.uk
