The download contains a copy of the install disk for v. 2.0 with a
crack patcher included. Version 2.0 of this tape� mounting package
allows users of System 7.5 to mount volumes that are as large as 4 GB.
Users can access files directly from tape.

> DeskTape 2.0 is a one trick pony. As its lone trick, DeskTape mounts
> DAT tapes on your desktop as normal, albeit slow, Finder volumes.
> You can do most anything with a DeskTape volume that you can do with
> any Finder volume, with a few exceptions. Most importantly, because
> files on a DAT are written sequentially, you cannot mount a DeskTape
> volume and edit files stored on the volume. Similarly, you can't
> reclaim space from deleted files. Finally, you can't (or shouldn't)
> share a tape over a network because of the ways networks interact
> with tape drives. In addition, you'd be wasting time to launch
> applications from the tape or rebuild the desktop on the tape
> because you could grow old waiting for the process to finish.
> Interestingly, Optima gives instructions for playing QuickTime
> movies from tape, which apparently is possible if everything works
> just right (and there's a full moon).
