From your example I do not see that the cover picutre files actually have the name of the folder of the music files.
Cover:
folder:
There is something extra in the folder name which means that folder name and cover file name do not match.
Now you have to tell us which part of the folder name has to be left out or whether you want to rename the cover files so that folder and file names match.
The general background:
There is an action Import Cover from File – Mp3tag Documentation
to import covers.
So if the cover file name and the folder name would match 100% you could use for the cover file name the
Format string: e:\covers\%_directory%.jpg
It will become very tricky if you want MP3tag to guess which is the correct filename.
Actualy the numbers represent the date, 5th of November for example, so can they be left out of the String?
So Actually
IF Path contains E:\New music\MUSICCITY Replace/Add MUSICCITY.jpg from E:\Covers IF Path contains E:\New music\Crate Diggerz Replace/Add Crate Diggerz.jpg from E:\Covers
