I have 5.6 gb of other data on my ipad?

I have a jail broken ipad and i installed a ds emulator but when i downloaded a rom called pokemon black from safari i spamed the open to ifile and nds4ios button when it was done downloading because every time chose the option it did nothing so i did the dumbest decision ever and spamed it now i can't even find the files on ifile so i can't even delete it any way to delete the ROMs i unintentionally downloaded without wiping my ipad clean but if thats my only option then i have to wipe it beacause i might have copies and copies of pokemon black i can't retrieve
