I connected the N7 to my Win 7 PC, windows 7 explorer shows it as "Digital Camera Nexus 7", I click on it and I see "Internal Storage" with DCIM and Pictures folders. I tried to create a new folder and I get a popup that says "The folder could not be created in this location. The device has either stopped working or has been disconnected.
What do I need to do to create a folder so I can copy files from the PC to the N7?
