I know this probably gets old in here but I am a pro photographer and the unthinkable happened during a very stressful shoot week back in November. I re-formatted and re-used a memory card....that was not backed up onto disc (I KNOW!!!!) - and it had the birde's portrait session on it (most of the session)....ZAR recovered ALL 115 files....even after I re-formatted and re-shot two more weddings on the same card.....OMG this software is great!!! What's even better - the bride has no idea nor does her maid of honour who's wedding I'm hoping to shoot....I would have been a dead man without this software!
Also - Canon User's that do not have Adobe CS.....you can read and adjust the saved CR2 (RAW files) that recover as a TIF - by simply using ZOOMBROWSER.
