My only concern is that I have 4,000 books and so scanning the entire device each time something new is added will add up in terms of time quite quickly.
Covergen seems smart enough to check whether the files have been processed previously.

The first run did take a few minutes, but all successive runs were near instantaneous for 3300+ books.

Also, it only works on JPEG covers as far as my experiences go. @geek1011, any idea if it works for PNG covers?
