Trying to make some files I had in a VM unrecoverable, I ran CCleaner in the VM and deleted everything I can from the inside, deleted the VM. And then I found out OneDrive had them, deleted it from there and off the PC again. Ran everything from my Recycle bin through bit defender shredder, recovered all my files through Recuva and did it again about twice.
I'm wondering if there was a free program I can use that will make everything non-recoverable. I want the most amount of "passes" I can get, I mind how long it takes. Unsure about the number of files that I have to delete but I'm not extremely worried about time.
What I would love to get your thoughts/help on is, what's a good file shredder I can use and a recovery system to test to see if any files are recovered. Thank you so much for your time and I hope you have a wonderful rest of your day! :)
