How to see Picard's "Total Disks" tag in MP3Tag?

[Freso]

@InvisibleMan78

BTW: Mp3tag shows the Picard «Disc number» and «Total Discs» combined in one value as “1/2”

If you look at Appendix B: Tag Mapping — MusicBrainz Picard v2.11.0rc1 documentation you’ll see that ID3(v2) (and APE(v2) and iTunes MP4) tags, in fact, only have one value for storing both the current disk and the number of total disks: TPOS. So ID3 tagged files do not have a way to separate out the two natively, which is why both values get stored in the same tag.

There was some more discussion about this (though for track numbers) in another topic:

TAG format varies from time to time / how to set standard for tagging

Let me reply for all tags, “standard” tags and MB specific tags, here. As for this discussions with standard tags I mean tags that are either formally standardized or are pseudo-standard as they are commonly used by players and tagging software. Standard tags: Looking at the output above, there seems to be a TRACK tag. For some reason MusicBrainz Picard just can’t make up its mind and writes it all different all the times, the developers must be crazy, right? Just that there is no single TRACK…
