Hello List,
Here is an archive file whixh is bigger than a floppy size.How do I make it
span floppies in the manner of Winzip? Also, I have difficulty copying spanned
zip files off floppies. How do I do that ?
Help,please .

I can tell you what I do to separate very large tar/gzip archives into cd sized chunks. It's not exactly like winzip's span floppies. But it should do what you need.
I'd use the split command. Which with an existing large file (lets call it archive.tgz) that I wanted to split into ( lets say 1MB ) pieces...
$ split -b 1m archive.tgz split_tgz_
I chose the output prefix "split_tgz_", But it could have been anything.
the output of the above split command would be files named:
split_tgz_aa split_tgz_ab split_tgz_ac split_tgz_ad etc...
Put the output files on as many floppies as it takes...
To restore the archive.tgz file to a usable state from the floppies,
copy all the split_tgz_* files from all the floppies to a single directory
on your harddrive. Then from that directory the command:
$ cat split_tgz_* >archive.tgz
should rebuild the original archive.tgz file...
For more details try:
$ info split
and
$ info cat
Yes,that does work.But what I was looking for was not just meeting an actual need.But a technological question as to why Linux can't do it or doesn't do it or hasn't thought fo doing it ? What you suggest is a two way work .But Winzip has been spanning floppies for many years and it appears so simple a task in Windows.Why this feature not in Linux ? I guess because of it's clumsy mount and unmount ?
