I used to be able to right-click on a file or folder in Explorer, and I would see mp3tag in the context menu. This made it enormously convenient to launch mp3tag with those files automatically selected for editing. Now this feature is gone? Or did Microsoft break something?
There have been several discussion threads about this, especially if you have moved to Windows 11. See if one of these topics fits your environment.
