Hi. I've searched if my query has previously been covered but I found no info. If I've made a mistake I apologise.

I'd like to automatically add Disc Number to the track number as you can do via the Windows version, e.g. Multi disc set of four: Track two (of 14 tracks) from CD1 would show as: **01-02/14**. I use this for some devices that do not sort by Disc Number. Otherwise I'd get all the 1s, then all 2s etc... I hope I'm not too vague.

Thank you.

Hi and welcome!

If it's really about prepending the disc number to the existing track field, then you can use _Convert → Tag - Tag_ for `TRACK` with `$num(%discnumber%,2)-%track%` as formatstring.

If you have something different in mind, please let me know 🙂

Thanks for replying. Yes, this formatstring worked like a charm. Great!!! This makes it so much easier to sort. Again thank you.
