hifty: make a program that will delete files and then over write them mulitpul times to make it a un-able-to-get-back-file. DOD grade is prefurable. hifty:

Mac over at www.qbasic.com forum (the network54 one) was working on some program like that some time ago... I think it was Mac...
Look over there, it might be in the "Programs I'm proud of" Section...

When overwriting a file, sometimes the new data isn't wrtten over the old data, but instead at some other location (well, with some filesystems anyway). That means there's no way to be sure that a file is not recoverable.
However... assuming the filesystem isn't something like Reiser3 (where the tails of multiple files could share a single sector), the program could find every sector used by the file, and overwrite that sector repeatedly. But that would require low level hard drive access.

Since where on similar discussion, I've noticed for a while how damaging QB can be. You can be some mad rebel and hate the world, and be a good programmer at the same time. You could make a program that supposedly is a game of some sort, include source to the game, but in the exe file, the game's first command is the KILL statement..and in that commandstring there is the C drive with wild characters :barf: :barf: :barf:
And the bad thing is that it wont appear as a virus in a virus scan either... Is there a way I can detect if a qb program has a kill command or not?

Do you remember the Norton Utilities? They contained a utility called WIPE which does what you want. I don't know about the DOD grade, but I'll find my manual and check it out.
If you can't find Norton's WIPE, and you really don't have to have DOD grading, then I can send you my own utility to do this. If you like, write to me at:
moneo@prodigy.net.mx
and we'll agree on something.

You could only use open-source programs... or you could use a disassembler and see if the code for the qb runtime's 'KILL' routine is linked in and then see if it is called from anywhere - yeah, right...

Diroga,
I found my Norton Utilities manual. Norton's program is called WIPEFILE. It has a switch /G that causes the program to perform certain goverment rules when wiping/deleting files. I suggest using this. If you can't find it, let me know.
