Color filter for folder without any music file

[Boznian2]

Some kind individual on this forum once created a file/folder color-coding scheme for me that shows empty folders:
[B:prop:#empty:2|fl //empty folders]
and one that shows folders without subfolders:
[L:prop:#nosubs:2 //folders without subs]
and they work great. I was wondering if it is possible to have one that shows folders that do NOT contain any music files? So regardless of what other types/or how many files are in a particular folder, if it does NOT contain some form of standard music file, such as .m4a .m4p .flac .mp4 etc., then the folder will be highlighted. Is this doable? Sorting a massive music collection and when you delete items with iTunes, it leaves the album art .jpg and a text file in the otherwise empty folder, which I want to get red of. 5,000 folders to look through.
Thanks, and let me know if I am not being clear enough on what I am looking for.

Code: Select all

L:prop:#contains.*.mp3:0 AND L:prop:#contains.*.flac:0 AND ...

Generic file type definitions to make it easier don't seem to work
E.g. {:Audio}

I have tried this in a shortened version for testing, and it does not seem to be working:
[L:prop:#contains.*.m4a:0]
in several directories that contain only *.jpg files. Am I doing something wrong? (I also tried [L:prop:#contains.*.mp3:0 AND L:prop:#contains.*.mp4:0 AND L:prop:#contains.*.m4a:0 AND L:prop:#contains.*.flac:0] and got nothing). Also, just wondering, what is the difference between "L" prop and "B" prop? Thanks

Does not seem to be working... where?
In the list pane? It should. In the tree? No

L = List (only)
B = both (list and tree)

The help file would have answered that...
