Default [Q] Moving Apps (App Data) to External SD Card

When you check out an app's info, there is an option to "Move to SD card". When I do this, I see that the available internal storage space really does free up. I tried finding the app data in the external sd, but no new directories are made and the size of the "Android" folder in the external sd remains at 32 bytes. So, where is the app data in the external sd?
