This program needs a feature for copying different versions of tags between themselves.
For example I have old MP3's that have only ID3v1 edited and I want to copy that version of tag to ID3v2 and then remove it. I can't do this with MP3tag... In the best case I can remove ID3v1 and then try to write ID3v2 from the file name.
Vic, you can already do this. Go to the options and under the 'tags','mpeg' section, make sure all boxes are checked at the bottom under ''remove'. Under 'write', check only 'ID3v2'.
Now simply right click any file(s) -you can do more than 1 at a time- you want to upgrade, and select 'tag cut'. After the tags are removed, right click the same files again, and select 'tag paste'. The program will replace the tags, but only in the new format !
If you want both ID3v1 and ID3v2, then leave both options checked under the 'write' section.
