Hi all

 

Running on Windows 7 Ultimate, 64-Bit.

 

There seems to be something eating up my space in my C: drive voraciously. The main problem is i cannot locate the actual files itself that occupy the space (with the view hidden files & folders ticked on). I'm not sure if this is where to ask it (if it is a windows installer-related problem or something else). 

 

To start off, I installed a game (The Sims 3) and its other expansion packs. I set them to install on the D:/ drive as follows: D:\Program Files (x86)\Electronic Arts\The Sims 3

 

My C:/drive disk storage at the start (before installing The Sims 3) was at: 315GB/465GB

 

When installing an expansion pack, a prompt to update the files pops up (which is needed to install them) I clicked yes and in doing this, this consumes about 3-4GB of space on average on my C:/drive

 

By the time i noticed the problem, i had consumed about 39GB (275GB/465GB) on my C:/drive. I find it is eating my space too much, tried to find the files manually on the C:/drive to no avail.

 

Also tried:

-Defragging (using Aus Logics Disk Defrag)

-CCleaner

Which didn't remove much space at all (about 100MB only)

-I don't hibernate my PC often (i don't leave it turned on either, turning it off when not in use) so i disabled hibernation via cmd (powercfg -h off), freeing up about 13GB of space. 

 

Also tried using WinDirStat, an application that shows used space allocation on the C:/drive. It only shows that i used 51GB with the breakdown being:

 

C:/Windows folder taking the most space, at 20.9GB - followed by my pagefile.sys at 15.9GB. C:/Program Files at 5.4GB, C:/Users 4.0GB, C:/Program Files (x86) 3.3 GB, C:/Program Data 1.5GB, the rest occupy less than 1GB...

 

Windows 7 64 bit system requirements uses

20GB http://windows.microsoft.com/en-PH/windows7/products/system-requirements

 

Still it doesn't add up to my current space that i am at in my C:/drive? 275GB/465GB (190GB consumed) so apart from my recent 39GB loss, there is something else eating up my space? How can i find the files that take up the space?

 

Edit: I think i may have found the culprit. I ran an elevated cmd prompt: vssadmin list shadowstorage. It shows Used Shadow Copy Storage space: 139.6GB (Am new to Windows 7, as a Windows XP veteran i didn't know that Windows 7 has this feature of shadow copies). So that explains my 190GB unallocated space (139.66+51.1 as WinDirStat reported)

I got to that article as well, thanks :) I managed to free up quite a lot of space (139.66GB)
