[WPCentral Question]

hi i am using lumia 730(India) developers preview.
my system files are consuming around 5 gb and app of 1.8 gb which is not the actual case. so how can i over come the problem, i dont hav much apps on internal storage.
except whatsapp of 800mb none of my apps go beyon 50 mb if i talk about internal storage.

but yes i have a 32gb of external sd card contains games like , fifa, gt rasing 2 and all

in nutshell, how can i recover space for my internal storage as if right now i have only 100mb(fluctuating 20mb up and down)
