When did this happen? App update? Android update? After rooting? Can you recall what you did just prior to this happening?

All of my folders as well as the default folders have disappeared. When I open S Note now, it just says "0 notes." I have a Galaxy Note 10.1, bought early June. The last time I saw my folders and notes intact was last Friday, 7/12. Help! I lost a lot of important work!
