How to repair pictures and videos ?

I have Replendence Undelux, which is similar to WFW311 & older Norton Protected Recycle Bin. Opening its menu: I was surprised at the amount of delete, copy, delete, copy, writing, writing, writing that Windows and also other programs do to both OS and data partitions.
Addendum -- I modified my wording, after a couple of posters posted their goodies :)

But its not working for me.

I was backing up a very good point that OvenMaster made in an earlier post.
Now, returning to topic of recovery: I'm waiting for sources in the know to tell us [then also I will know how].

You could try PhotoRec. A long shot and won't help if part of the file has been overwritten.
