Move music file one level up (from directory to parent_directory)

Hello! I need again some help here.

I need to move some music files which are in dedicated CD01, CD02, etc folder one level up (into de _parent _directory).

Folder structure it's something like this:
C:\Users\stoic\OneDrive\Desktop\Audio\2Pac\2Pac - All Eyez on Me [2004]\CD01\Song.flac

Should become:
C:\Users\stoic\OneDrive\Desktop\Audio\2Pac\2Pac - All Eyez on Me [2004]\Song.flac

Keep in mind that "C:\Users\stoic\OneDrive\Desktop\Audio" could change.
And I need this done by an action not tag to filename (because it will be added into a sequence of actions..)

Thank you!!

Try an action of the type "Format value" for _FILENAME
Format string: ..\%_filename%

Please be aware that if you move

to the same "one level up" folder
C:\Users\stoic\OneDrive\Desktop\Audio\2Pac\2Pac - All Eyez on Me [2004]
you will overwrite one of your tracks Song.flac, because you can not have the same file twice with the same name in the same directory.

Agreed.

If you are going to do this, you should consider renaming the files to also include the disc number and track number. Something like %discnumber%-%track%. %title% helps keep the filenames unique per folder.
