>Hi.. Eric, thanks for your information reply, but is it possible for me to backup large size of files that will need more than 1 floppy disk and how does it work when it decompressed? .. thanks again

it has the span feature that will ask for multiple floppies. When decompressing (exactly like when you use PKZip or WinZip), it will ask for the last floppy (to read a kind of catalog) and the ask for the first, the second, ... up to the last.
