Is MP3Tag capable of extracting a certain part of a tag, and copy it to another tag?
I have titles such as:
Cello Sonata No.1 in E minor, Op.38 › I. Allegro non troppo
I want the part before ' › ' to be copied in a custom tag named 'Composition',
and the part after ' › ' copied to a custom tag named 'Movement'.
So 'Composition' tag becomes: Cello Sonata No.1 in E minor, Op.38
and 'Movement' tag becomes: I. Allegro non troppo
(title tag is not to be changed)
I found an action called "split field by seperator", but I think this can only split to multiple fields in the same tag?
tia!

Yes, that's a main feature of Mp3tag.

Fantastic!
(so I just should have been searching for 'import' instead of 'export' 😉
Thanks guys!
