DiskAid Or if you delete files on your computer by mistake, and want to retrieve your backup copy from your iPhone/iPad, you find you can’t.

A little program called DiskAid will let you retrieve those photos.  It saved me from losing about 900 photos today, so I’m very happy with it.  The function to copy photos is available in the “free” version of DiskAid.  The registered version allows you to additionally copy music, videos, SMS texts and other data.
