- You should compare it with PKZIP 1.93 - theoretically it should have
- the same compression ratio, unless they have invented something really
- new, which I strongly doubt...

- Gosh! But that is STUPID!!! And there were thinking about
- multi-platform support and other some such - how are they going to do
- that unider Unix? They seem to have selected the most silly one
- of the possible solutions... :-(( I thought that only BACKUP that
- comes with DOS is that silly...

- What's going to happen is that people will use ARJ for multi-volume
- archives... :-) I doubt that the Info-ZIP product can be made to use a
- more intelligent way to handle multi-volume archives if it wants to
- stay compatible... Unless they decide to implement both ways - the
- silly one in the new PKZIP and a more intelligent and straightforward
- one...

- Hmmm, a better solution would be to just skip to the end of the
- compressed -image- of the file that contains the bad sector and to
- continue with the next file from the same disk...
