Hi! Need some recommendations about file shredders... What shredders do you use and why?

I use Shred Agent. I'm satisfied with it. It deletes temporary files and cache while working in background. No issues or errors were detected...

File Shredders
 

I use Secure Shredder a built-in tool in Spybot - Search & Destroy

The Secure Shredder will permanently remove files you won't be able to recover files after using Secure Shredder.

You can also try other freeware's like:
Simple File Shredder : Simple File Shredder is a utility that securely deletes your files so they cant be restored using recovery software.

Tiny Shredder : Tiny Shredder is a small file utility that will completely erase the contents of sensitive files and folders that you specify.
