Quick question, i'm trying to apply these images to folders residing on my comp, i've tried, both folder.jpg and "file".tbn and neither is working.
I've got it working when naming them 'folder.jpg', but I also noticed that when you've had another icon before, it won't update right away.
When you delete the 'Thumbnails' folder inside 'UserData' the thumbnails will be reset and it'll look first for a 'folder.jpg' inside the folders.
Do note that this wil also delete the thumbs you downloaded with 'Get Thumb'.
Therefore I find it more comvenient to use only 'folder.jpg' inside the folders, so they never get deleted.
