I have just upgraded my windows 10 installation with the new features update. On return, my hard disk was full and i have identified that it was caused by files with no extension. Around maybe 300 in total, each file is around 200mb in size. Because of this, my hard drive is full. Here is an image:

Great if anyone knows anything about this and what to do.
