I'm sorry, but there is no way to detach all files from more than one message at a time.

To detach all files from one message, click on the arrow to the right of the Save All button, and select Detach All.

Hi, Thank you, "Attach Extractor" 100% usefull for my version of Thunderbird. Deattach in one click to selected folder. Many TNX for support
