I am using Windows Explorer on Windows 7.
In My Documents there's a folder 02 KOOP. If I go there using the adress bar:
D:\users\username\My Documents\02 KOOP
I get a view of my subfolders and some files:

However when I use the Documents shortcut under Libraries, and then go to the 02 KOOP folder, all files that are located in all subfolders are listed in one big list. When you view the file properties, the actual location is shown:

This is the only subfolder of My Documents that has this behaviour.

Did I accidentally change some setting, or is something wrong?

Is this some setting I accidentally changed?
