disappeared bytes

Hi,

I hope this is the right forum to ask my question.

I have a strange problem. I have 3 hard disks. In fact I have 2, since 1 of them is partitioned (C: & D : . On C: I have installed my operating system en D: is where I keep my data and install programas. F: can be ignored since this is my old disk which I rarely (never) use any more.
As said, D: is where data is stored and where I install my programs, to avoid my c: drive where the OS is running to get full. Now, I've noticed that my C: is getting full anyway. Not knowing how this could be (ok, I've installed some programs on by mistake) I went searching on the drive where all this excess data could be stored.

I thought I was on the right way, when suddenly, whereas the previous folder contained about 82Gb of data, the sum of all the folders and files in that folder are only about 22MB.

I've made a little video to show you the problem. I think the best thing is to watch it in full screen.



I hope someone can solve this.

(Edit : Forgot to mention : Hidden files and folder are viewable)

In folder options is "Hide protected operating system files" unchecked?

82GB of Temporary Internet files If it is all genuinely Temp files which you don't need I would consider cleaning them out with Ccleaner. No way should you have that much data there....
