I am running Windows File Recovery on my 1TB M.2 SSD and I am appalled at how much data is recoverable. When I delete something I expect it to be deleted. Gone. Irrecoverable. Can I do this with already deleted files?

I was thinking and my method might be to run all of the files I want to delete through an application I’d write which would 0 the files first.

Marking this as data recovery though it is more the prevention of data recovery.
