Why is Cubase creating double folder?

I create a folder for a session, then see later on that it has created a duplicate folder but with only “Track Pictures”-folder in it. I have never seen this before.

Cubase 7 adds a new folder to store the pictures of instruments in the track list. If you are not using pictures the folder is empty. :smiley:
