Seriously? When files are deleted, their sectors are simply released to

No worthwhile filesystem will allow you to read a block of disk that you
haven't already written to. Once you've written to it, any existing data
that was there is overwritten.

The same isn't true for block-level access, but as a rule that requires
admin access, and once you have that all bets are off...
