My vita recently started acting up and failed to install some games correctly. They had been sitting on my memory card for a while without getting and install. When they failed to properly work I deleted them. The games gave error codes or simply failed to be deleted on the first attempt but I managed to get rid of them after I hit delete two or three more times per game. Recently when I tried to re download one of the deleted games I was told my memory card (32 gig) was full. I though that was odd because I hadn't even finished installing all of the games I had before my vita started having problems. I checked the content manager on my vita and it appears that I now have 7.7 gigs of "other-system use" data occupying my memory card. This seems incredibly unusual and I have no idea how to clean it out. I am about 70% of the way to a platinum trophy in persona 4 golden so I'm reluctant to try anything that would reset game saves. Can anyone give me any advice?
