Thanks for reporting, it is related to tag editing under Folders node only, tracked as: https://www.ventismedia.com/mantis/view.php?id=18624

Hi,
I came across some weird behavior related to the handling of album covers where image files stored in the folder of a track are incorrectly deleted and recrated if artwork stored in the tag of a track is removed.

To replicate
- Create a folder containing an mp3 and image file called cover.jpg
- Store an additional image in the tags of the track
- Make sure that the tack properties show both the artwork stored as the tag and folder
- Remove the artwork stored as track
- Confirm the popup
-> The image file in the folder will be deleted and recrated with an incorrect filename

Edit: I made a short video to demonstrate the behavior, see [url=https://emalm.com/?v=CqWkn]here[/url].
