speaking of documents, it seems that the Nexus 7 has now stored my "documents" in 3 different document folders depending on when they were saved, the most recent being /storage/emulated/legacy/Documents ... the prior being /sdcard/Documents ... And prior to that just in /Documents ...
The problem is now that I want to access these files from my PC they are scattered in 2 different places with different versions in the prior locations that are older than the most recent ones in the new locations.
this also explains where a folder call "0" appeared full of photos, apparently it created a new location in the emulate folder and put a bunch of pictures there.
