Yes, it's the title of tracks but more importantly, it's the artist or group that I keep together alphabetically. ie all Adele together or all The Rolling stones together. The 3 numbers seem to be the only way I found some years ago to maintain this order when copying to USB.
As for the IBB script, I cannot find any way to produce a .mta file as notepad and notpad++ do not list this extension. Nor does Libreoffice. If you paste content into Notepad it becomes a text document automatically with no way to change it to a .mta file. there is software to convert from.MTA but not TO .MTA. It seems to be a file extension created by Samsung AllShare, a program used for sharing multimedia files between PCs, so I am completely stuck trying to use IBB's script.
My question to you now is, if I uninstall Musicbee and start from scratch will I end up with the same problem as these images are embedded in all my mp3 files?
It took me 1/2 an hour just to edit and delete manually some 9 tracks as it's scores or hundreds of clicks each time and if you click too fast Musicbee freezes.
Again I appreciate your thoughts and input Frankz
