Sharing files between users in 4.2.1 I have a Google Nexus 7, unrooted, running stock 4.2.1. I have set it up for two user and we seems to be enjoying it.

Recently I ran into an issue about sharing files. In User1's account I copied few PDFs into \sdcard\PDFs folder and was able to use it well.

When I switched to User2's account, I could not see the folder \sdcard\PDFs at all. Surprisingly, I could not see it even when through computer when Nexus 7 is connected as Portable media player.

I guess this can be achieved by granting sufficient access by escalating to root, which needs rooted device - but I am not sure.

My questions:


Are there any way I can share files between users of the same tablet without using Internet (like using email, dropbox etc) or transferring to some repository like PC etc?
If I root, can I change the permission to such user created folders and access files from other user's account or elevating as root?


Update: Found a link that asks same question - but the answer given is not applicable for files rather works for apps, not useful.
After a lot of trial and error, I  discovered that the Android/obb folder is automatically shared among users.

It's not ideal, but it's better than a cloud storage option for large files.
