hi i was wondering if anyone could tell me what these 2kb cod files are used for please (all the trascending ones), im wondering if theyre ones downloaded needed to run an app or just junk i dont need as the file size is so small, ive googled them but theres no info for them and theres no hint of what app theyre from in their titles so im uncomfortable to keep them on my bb but again uncomfortable to delete them incase a bunch of my apps stop working
