PC Tools has a wipe program that will either wipe individual files, or wipe all unallocated diskspace. It also allows you to choose the level of wipe (single overwrite, multiple, etc).

There has been considerable discussion on the MCIP list about how most *Mac* programs that purport to do this, like Burn, for example, leave stuff over in disk blocks. My understanding is that this is not a trivial problem, and it occurs in MUSH-DOS as well....

Actually not a problem for mess-DOS: just overwrite to the next multiple of the allocation unit size. Trivial indeed. What you must *not* do is just write to the end of current file ... you have to extend. Good idea too is to flush file buffers/reset disk subsystem before the next file writes so that buffer garbage doesn't get stuck in at end of last sector(s) of new files.
