I have files on my PC with names and addresses of clients that I need to delete after expiry. How good is the file shredder?
I have shredded the files using a free Ashampoo optimiser, which takes ages but claims the files will be totally unrecoverable, even in a pro lab. BD file shredder is much faster, but I don't know if the files will be recoverable.
To what standard are the files shredded?
