normally, all my tags are ID3v2. But sometimes older files only have IDv1 and no IDv2 tags. The problem is in MP3TAG I can't see both or could I? Is there a trick?
So my question is: How can I convert only this files not permanently with customization of MP3TAG but by using a script (convert ID3v1 to ID3v2) ( without overwriting existing ID3v2 tags!!)?
