Folder tree background images for different folders

Hi everyone!
How to do automatic change BG image for tree folder ?
I created images for each disc.
Example for C = image 1
For D = image 2
etc..

but folder tree does not work for changing images for each disc.

How to make this?any suggestions? or this works on opus 11?

plz... help me..

The file display (right panel) can show different images in different folders, but not the folder tree (left panel).

The folder tree is never really in a folder; it is always showing all of the (expanded) folders at once, so it is not affected by any per-folder settings.

You can set the folder tree background to an image of your choice, but it will not change as you change folders. Only the main file display can do that.

thanks))
