Good concept, poor execution

Pros: great concept and easy to use. This creates a csv file (a listing of all files) that are purportedly not used by your wordpress installation. With the CSV, you can write a script to delete all of the entries or have a very small website, you can delete the entries one by one.

Cons:
Using the list that was created, I wrote a quick bash one liner to delete the photos that were listed but many of the photos it flagged as not used, were in fact used by my insllation!

Fortunately, I had a backup of my files so I just reuploaded them but it was annoying.

I’m off to look for alternatives.
