- I have used zip followed by zipsplit to do this. This gives me one
- complete, independent zip file per floppy. The compression ratio of
- zip tends to be better than compress. It can also be told not to
- recompress files which are already compressed. The zip and unzip
- programs were posted to comp.sources.misc and are also available via
- ftp from agate.berkeley.edu and elsewhere.
-
- The disadvantage of this approach is that you need enough free disk
- space to build both the big zip file and the split zip files. I have
- handled this by backing up files in <gasp> related groups which has the
- added benefit of making it easier to find things in the backups.
-
- Has anyone hacked zipsplit to handle a sequence of raw floppies?
