I go into the Settings>Storage menu, and it tells me that there's 10Gb worth of data on my card. However, when I go to my card in File Manager, it shows nothing on the card. I have the hidden files option turned on, but it still shows nothing. Screenshots included. So, how do I reformat my card? I've searched the app store, but haven't found anything that can format cards. Google only turns up results for phones that have formatting options built in. Any help would be appreciated.
