What's up with my C ? Something fills it !

hello,
I can't figure what's happening with my C HD
it shows full, but when I look at what it contains it does not figure....



The added size on disk of the folders is less than 40 GB while it shows over 100 GB full



any idea about what's happening would be great help !

You should not expect the sum of the folders to match the total occupied space. There's a bunch of stuff that's hidden.

How much space do you have devoted to:

System Restore
Page file
Hibernation file

??

TreeSize Free - Quickly Scan Directory Sizes and Find Space Hogs

You can download Tree Size Free from the above link. It should tell you what's using the space. Your appdata folder is a good candidate.

Its the System Restore points. Delete them all, then make a new one in case its needed. You will be very surprised.

thanks for your answer ignatzatsonic !
here's what I found
no idea how to check on the hibernation file though
I normally never go to these areas, absolutely not up to any tweaks of any sort...







richc46 hadn't seen your answer, ok, will do
BUT WHY DID THIS HAPPEN ALL OF A SUDDEN ?
still curious about the size allocated to stuff... has something altered it ? cause I sure never changed anything there !

As rich said clear system restore and change max usage to a lower level like 10% that will free lots of space
Im using a small 60gb SSD so I have mine set to 5%

My guess would be that Windows has recently made a bunch of new System Restore points. You need to pull that slider back as Pauly suggests. You now have it using about 55 GB; 5 or 10 should be enough for a half dozen or so restore points and that's probably all you'd ever need.

You can change that page file (virtual memory) to maybe 2000 mb to save another 6 GB.

You can turn hibernation off completely if you don't use it. That would save you an amount equal to your RAM.

I think the command is powercfg -h off

Enter that command from an administrator's command prompt.

hibernation is set to Never.... so that's ok
I deleted the restore points and things are back to normal, thanks to all of you
the restore point I created uses a huge 95.22 MB so you're right, I can do a lot with the slider down to 10%

now would any of you be so kind as to explain (in plain english, I'm not very computer fluent) what is the difference between a restore point and a back up (which I make weekly to an outside HD) with window back up ?

A system restore goes back to a point in time making changes only to the OS and not your stuff
A back up goes back into time and changes everything,

but why is it that creating a restore point takes seconds while making a system image takes much longer ?
