File Shredding

The methods I've seen for file shredding seem pretty flukey. Can anyone tell me a good way to shred a file in C++?

Shred?

I think he means that he wants to delete a file so that it can't be recovered using a file recover program. I think that the way you usually do this is to overwrite the file with garbage information and then delete it.

Yeah. There are codes the DOD & DOE (US) use to make sure data cannot be harvested from a deleted file. The algorithm is called ERAPAT. SEarch for it on Google.

Highwater-marking is another feature of this as well.
Windows doesn't support highwater-marking

should help, thanks
