I've noticed a few times in different places, an empty folder called Keyboard. This seemed really strange, and I thought it might be malware or something, but then I ran into this very short thread.

The 3D folder referred to in the thread must be Maya 2013.

I have been able to replicate this behaviour. If I double click on a maya file, instead of file > open from within the program as I usually do, this empty folder will be created. Does this happen to anyone else? Why is this happening?
