Is there any way to view files saved on a Nexus 7 after it has reset itself for no apparent reason?

[AC Question]

I charged my Nexus 7 today and when I took it off the charger I found that it had reset itself. I cannot view the files (documents, epubs, photos) that I had saved on the device - it appears that they have been deleted.

Welcome to Android Central! You mean it did a spontaneous factory reset? Did you have to go through the Setup Wizard again?
