Okay, here's an easy one for you. 😀

I have a box set of CDs.

I have an action to replace 00 in the album title with the disc number, so I can globally number the complete set in one hit.

However, the set is broken down into sections (orchestral, chamber music, piano music, etc.) & I'd like to append a two-digit number to each disc, starting from 01 for each section.

In other words, if I select 5 of the discs & run the action, it will add 01, 02 etc. to the end of each album, based on either the track numbering or the disc numbering, starting from 1 each time, in much the same way as the discs are numbered in each section in the finder:

I'm not expecting it to know where the sections are, I'm just assuming it will number the discs I've selected, starting from 01 each time I run it.

So, for example, Concertos, here:

Will end up like this:

So ..... I think I get it.

An Album field contains something like DG 08. V02: Concertos. Let's call Concertos the descriptor. So starting from 1, whenever the disc # changes you add 1. Whenever the descriptor changes you reset to 1. If those are the rules, you can sort the files correctly, select them all and do it at once. Correct?

... correct or not if you want me to write the action ... and test it first ... please download the Dump Metadata action from the web resources page (off the Help menu). Select the entire set of files and run the action. Send me the produced zip to support@2manyrobots.com. I have an action which uses the dump to recreate the files (without audio). All paths, filenames and metadata will be recreated. That way I can test this thing without spending a lot of time creating dummy files to test with 🙂

(I'm doing the dump now anyway, as you specifically requested it. 🙂 )

Ah, bugger. That's a cock up on my part. I started to think ahead & forgot to finish what I was doing.

Every album will start with DG, followed by the volume number, followed by the descriptor.

Let me finish the basic tagging & I'll send you another dump. Sorry about that.

So I just ran the action on your 2nd dump and it seems to work. I end up with the following different Album fields. The only one which look a little weird is the Concertos which were already follow by a number. Is this correct. If it's hard to see from the album list, run it on the files where it is a little easier to comprehend.
