I'd search this subforum using the term "param.cfg". I've found a couple of post here saying that deleting that file resets the player just like other Cowons. I don't have the X7 but on the Cowon iAudio 9 I have I once deleted the param.cfg file and then formatted it using the SDFormatter. After that everything was reset to the factory settings. If there are any demo files it won't restore those but all the folders should be restored the same as new.
I believe one of the moderators, musichound, has an X7. He would probably be able to give you more exact directions if he sees this. You may want to wait to see if he has more. If he doesn't respond in the next day or so I'd bump this thread. Sometimes life keeps us busy and we don't see everything at the time of the first posting.
