I used a file recovery program that was on a cover disk last year sometime. It might not have been a PCA cover disk though!
The program was a free trial of about 16 days I think. It included a program to allow you to permanentley delete files and a program that could scan your hard disk to find files that were deleted but could be recovered. The files could then either be opened or deleted. The file deletion part put an icon on your desktop that you used to delete the files. A bit like another recycle bin.
The program worked extremely well and I would like to purchase it.
But I have totally forgotten what the program was called and cant find my cover disks anywhere! (I have moved house and they have got lost).
If any one has any idea what the program might have been you will be helping me out a lot.
