Hmmm, are you sure then that DriveSpace's empty volumes are all nicely
filled with zeroes?

What's funny in this? Neither deallocation nor allocation doesn't result
in wiping memory, it would be just a waste of time.

Shareware? I don't think so. I bought my Stacker 3.12 with Caldera
DR-DOS 7.03 (which you can download and use non-commercially for
a trial period not limited to 90 days, whatever it means). I know
also that you can buy Stacker 4.0 with IBM's PC DOS 7.
