Alright so I was messing around in ifile looking in clash of clans, so when I clicked on a.. In csv the link sent me to imtg. Sorry about the names I don't know the " programming" lingo, anyway what happened?
When you click a file type the device wil open it using a program that can open it. IMtG just happens to be able to open csv files, it probably read there was nothing in it but that's probably what happened.
