How to tag albums when the album name appears as part of the path?

I'm hoping someone can help me with tagging my mp3 files. I have a large collection of mp3's that I wish to tag. The album appears as part of the path. I am trying to use "Filename - Tag".

As a simplified example, suppose I have my mp3's in C:\music

Some tracks are located in:

C:\music\Album Title\Track1.mp3
C:\music\Album Title\Track2.mp3
C:\music\Album Title\Track3.mp3
...
etc

Others appear as:

C:\music\Album Title\Disc 1\Track1.mp3
C:\music\Album Title\Disc 1\Track2.mp3
C:\music\Album Title\Disc 1\Track3.mp3
...
C:\music\Album Title\Disc 2\Track1.mp3
C:\music\Album Title\Disc 2\Track2.mp3
C:\music\Album Title\Disc 2\Track3.mp3
...
etc.

The album title always appears as the folder name immediately after "C:\music" in the path.

I've tried using

C:\music\%album%%ignore%

But it's been unsuccessful. It doesn't seem to work for the type with multiple discs. I'm hoping to find a single mapping that works for both types since I have many folders to tag and it's not easy to separate them all.

The term %ignore% will create a new custom field. But what what help is to use a Quick Action with the type Guess Value and the term C:\music\%album%\%dummy%.

EDIT: Corrected the typo in my original reply for %dummy%.

Thank you! I'm new to the "Guess Value" function. Do I enter C:\music%album%%dunny% as the Source Format or the Guessing Pattern? And do I just leave the other field blank?

Posting in case it's helpful to others. Guess values worked!
I used Source format: %_path% and Guessing Pattern: C:\music%album%%dummy%

Thanks MotleyG!

Please note that the correct name for the dummy field is %dummy%

In the converter try:
Format string: %album%\%dummy%
