I am setting tags for an audio book that has +70 individual files, saved in multiple directories based on the CD they were recorded from.
Example
Martian\_d1, Martian\_d2, Martian\_d3, etc.
To set the filename (thanks to another person here helping me) I am using…
The\_Martian\_\_$num(%\_counter%,2)
This is working great for the 14 files in d1. When I move to d2, I’d like to start the numbering at 15, so all files can be moved to 1 folder for ease of use. Is this possible?
Clarification. Folder Martian\_d1 has..
The\_Martian\_\_01.mp3,
The\_Martian\_\_02.mp3,
…through…
The\_Martian\_\_14.mp, etc.
I would like to begin the numbering in the folder Martian\_d2 at 15 so it has…
The\_Martian\_\_15.mp3,
The\_Martian\_\_16.mp3, …

To start with no. 15, try
`The_Martian__$num($add(%_counter%,14),2)`

For future readers:
In this case the value 14 will be `$add`ed to the current value in `%_counter%`.
Since the dynamic variable `%_counter%` starts with a value of 1 for the selected track #1, the starting value is 1+14=15.

You can, of course, proceed folder by folder and use Ohrenkino's suggested solution. However, you could also load all the folders and complete the process in one go.
If the individual CD folders (and no others) are located within an parent-folder folder, simply load the parent folder into Mp3tag.
If this isn't the case, you can select the individual CD folders in Windows Explorer and drag them into Mp3tag. You can also add the folders via the "Add directory" option in the menu.
Then, arrange all the files in Mp3tag in the correct order, mark them, and apply the format string `The_Martian__$num(%_counter%,2).`
