Fixed: No new pictures or videos were found on this device

I’m using Windows 7, trying to transfer photos from my digital camera to my laptop for the second time, but the Import Pictures and Videos wizard won’t let me. After I connect my camera and choose ‘Import pictures and videos’ from the AutoPlay dialog box, I get a message from the Import Pictures and Videos wizard that ‘No new pictures or videos were found on this device’.

Although it would have been simple to just treat the camera as a mass storage device and browse the files in Explorer, I wanted to use the wizard to create a folder for each date. Why can’t we have a button to import the same images again and again, as many times as we want?

Disconnecting and reconnecting the device didn’t help, and deleting the files and containing folder from my computer didn’t do it, either. Obviously, something was keeping track of which images were being transfered. So I started digging around and found this interesting file in my user folder:

C:\Users\[username]\AppData\Local\Microsoft\Photo Acquisition\PreviouslyAcquired.db

I renamed it to PreviouslyAcquired.db.old, then reconnected the camera and went through the wizard and lo, I was able to import the pictures a second time.
