[AC Question]

I am attaching my Nexus 7 (2013) to my PC via USB and since the latest Android version, I can't see all the folders and files which are on the tablet. YES: I am swiping down and using "file transfer" and not USB charging when I attach it. Have not seen a solution to this problem. YES: I have cleared cache partition: no different. Have screen dumps of the view on my PC vs. what's actually on my tablet. I need to transfer my photos to my PC and don't see them when attached.

Nexus devices do not connect to a PC as regular SD drive. They use a special protocol intended primarily for media files. So you won't be able to see all files an directories on the PC.
If your device and pc connected to the same local network, you can use the app AriDroid. On PC you'll get web interface to the your device, and full access to directories and files.
