I have an old saved file in my thumb drive with strange name. The file types are all different strange name too. All these files cannot be opened. They cannot be deleted too. When I click to delete, it says: "The file (strange code) is a system file. If you remove it, Windows or another program may no longer work correctly." When I click Yes, it says: "Could not find this item. This is no longer located in E:\. Verify the items's location and try again." Then there are files which cannot be deleted and the remark is: "The file name you specified is not valid or too long. Specified a different file name." How can I delete all these unusable files?
