This is a fantastic program. I was out from 2am to 5am last night shooting a grape harvest, and when I got home discovered no files were visible on the 16GB card I had been shooting on. I looked for a recovery program for OSX – the first I tried recovered the files, but the JPGs weren’t viewable; the second found them and I could see thumbnails, but then it wanted $150 to register it. Then I found this! O Frabjous Day! It worked without a hitch (and much, much faster than either of the other two I used), and now I have all my files again.
