Hard Drive inexplicably double overnight

[philipt95148]

I keep Recorded TV in 1TB HD and deleted recordings when done.
It has been at 50% usage for a long time and suddenly overnight increased to almost double.

I looked up all hidden files and could not see what could have caused this.

Has anyone experienced this?

TIA

Install WinDirStat

That works.
Windows created a video folder and populated it with over 300gb of live tv records of 2,3 gb each. I don't know why but this was after a security update that was pushed through my system even though I set it up NOT to update.
Do you happen to know how to stop all updates, including security updates?
Thanks

Stop the Windows Update service and disable it.
