Hi
little bit of infor for you first
When u delete an item from your pc or the recycle bin the file is still there on the pc, all that happens is that the path to the file is removed and that part of that hard disk is marked as " writable space" the more you put on the pc then this will overwrite previous files that you deleted before, This is why recovery programs work so good because the core content is still there.
You can use a program called Recuva by Piriform for example that can recover deleted files, content pictures etc,
This will take some time so please dont expect miracles instantly. The bigger the hard drive the longer it will take.. 80gb HDD takes about 2 hours on my slow laptop and if i remember right abougt 9 -10...
