Filter by embedded album art

Hi there guys.. i've been looking for this a while in the forums and no luck, i hope someone out there know the answer.

How do you filter files by embedded album art? For example: i wanna display ONLY the files that i have not yet attached the album art so the task is easier.

You can create a new column "Cover" via View > Columns..., set its value to %_covers% and sort by this column to group the files without cover art.

This column might already be there, you just have to activate it.

Hey thanks a lot..
