[Coco] Looking for a DECB directory utlity

[Tony Cappellini]

I used to use a great directory utility program under DIsk Basic.

We called it 'Z;  (this may not be the original name, but I can't
remember anything other than that)
It was something like Windows Explorer from W95 days (or Xtree Gold
from MS DOS).

It had two panels, where one side was the source the other was the destination.
It was great for copying files between floppies, renaming files,
formatting floppies, etc.

I remember needing the 64K upgrade to run it.

Does anyone remember or have this program?
