Only thing I would like to see added to Recuva is the ability to also sort on file type/extension.
Have just had a calamitous month with a fairly new WD 2tb drive that has developed several bad clusters, accidentally (autopilot thinking) overwrote part of the drive before doing a safety copy of several important files, now searching through 700K+ files to find the ones I need. .
Being able to do a sort on file extension without resorting to the search function would be a reasonable addition to the interface (only another column to add to the view structure)
