Where's the space getting occupied?

[Anudipta Chaudhuri]

I am running on Windows 10 mobile build 10166. I was trying to download a big file (Asphalt 8) from the store, when the connection went out. I cancelled the download. But the space on the phone isn't getting recovered. When I started the download there was 3.65gb free, and when I cancelled it's 2.61 Gb. I did this again after resetting the phone, but with similar results. Where's this space vanishing?
