Often, we want many of the files we have on our computer, due to their private and confidential nature, disappear definitively when they are deleted, and that they cannot be recovered even if recovery programs are used. For these cases you only need a tool like Necro Shredder.
Necro Shredder is a utility, totally free, that works as if it were a shredder, only that instead of physically removing and shredding the paper, it does so on the computer. Necro Shredder really does not delete the file, but overwrites many times in the physical space where the file was, so that its recovery is totally unfeasible.
You can free download Necro Shredder 32, 64 bit and safe install the latest trial or new full version for Windows 10 from the official site.
