Please, please, please! I really hope someone can help me, I recently opened the Quickoffice application and went to updates and upgrades, I then downloaded Quicksudoku to my phone, this then filled my Media Album (Images & videos) with files called Quicksudoku_set020 (I think there are over 300 of them!), the files all have an image of a broken picture which looks like it is a standard thumbnail for the phone. I have tried to delete these files without success, I have tried to move these files without success, everytime I try something a little key appears in the bottom corner of the thumbnail. Does anybody know how I can delete these files? I have tried opening them in Quickoffice, but cannot find which folder they are in. Am I just being really daft and there is a simple solution? I really hope so! Thanks in advance for any help.
