I uninstalled my apps and added them back a few per day, and kept checking for that file (weiqian_record.txt). It magically re-appeared after I reinstalled and opened MOBO PLAYER. It's a fantastic player to have around when no other player will open a file. MOBO PLAYER is free in Google Play, but I've found older versions are better and can be found at 4shared.com. 4shared has a lousy search capability, so use google and add site:4shared.com
to your query.

weiqian_record.txt "mystery".
