Windows 7 , C drive filling up on its own !!

I tried deleting the system restore points and cleaning all the junk and cache files.

Even tried managing the page index files and last time this problem occured i even deleted the hiberfil.sys and pageindex.sys ( something like that name ) . tried apps like WinDirstat and it pointed me out to the extra space being taken up by the " common files "

my C drive has filled up and common files are taking up all the extra space ( 47 Gb / 98 Gb )
and i dont think deleting them would be any smart ,
Please let me know what should i do ?

These are the screenshots of all the specs you asked for. :)

You need to drill down in Common Files and figure out what is using so much space.

The W7 system I'm on right now,
C:\Program Files (x86)\Common Files uses 495 MB
C:\Program Files\Common Files uses 282 MB

Mine is different but , The folder has a heck load of small size files , all equal in size..now i dont know which ones to delete and which ones to leave out.

You Windows 7 in C: drive is too small storage space.

Although you have 1 TB drive, you have used too big storage space for Games & Photos.

For the Disk-1 (2nd) HDD of 500 GB, you only use 170 GB or one-third of the HDD.

You can do a partition in the Disk-1 (2nd) HDD of 500GB

The best option is to move the partition "Photos" of 30 GB and "Games" occupy 60 GB.
Create 2 folders, "Photos" and "Games" in the Disk-1 (500 GB HDD) as folders, instead of partitions.
Copy the partition "Photos" on folders & files to Disk-1 "Photos" folder.
Copy the partition "Games" on filders & files to Disk-1 "Games" folder***option.

Do take note, do not copy both $RECYCLE.BIN and System Volume Information.
After copying, go back to 3-photos Device Management, and delete the partition "Photos"
As for the partition "Games" delete logical drive.*** option.

In this way you can deleted the partition "Photos" and extend your C: drive to have another 465 GB.
On the Disk-0 (the 1 TB HDD) click on the C: drive (to select) and
then right-click and select "Extend Volume". Choose how big that you want.

***You can let this partition to remain.
When doing the "Extend Volume" on the C: drive, you can take-over the "Photos" D: drive.

Note:
It is better not to delete the system restore points, as this will help you in case you encounter errors.
The System Restore points are created BEFORE installing new windows update.
If the latest windows update do encountered error, then you just do the system restore point before the update.

How did you just deleted the hiberfil.sys and pageindex.sys
They cannot just like files that you just deleted them.
Else the files will come back, if the deletion is not properly done.

This is an idea.
Your decision.

@Eric3742 : I deleted them somehow and now i cant find them, plus you are talking about relocating space from one drive to another , that wont fix my problem because the disk is filling itself progressively and its not stopping.

I even deleted all the system restore points.

Did you have any internet security or antivirus & malware to protect.

I use this "SuperAntiSpyware" to regular check on my laptop, even i do have a permanent Internet Security "Panda".
The SuperAnitSpyware is a free version, and i used it after surfing.
This software can remove all the malware, virus, etc.

Your computer is acting this way, due to malware &or virus, etc.
Go and download and install, and go to the bottom right, to download updates.
Then click on "Scan this computer" and select "Do a quick scan" in less than 5 minutes.

You will be surprise to see how many malware, spyware, virus, etc; in your computer.
In my laptop, out of 250 GB for Windows OS, it only uses less than 70 GB.

Your current situation is due to malware++ and nothing to do with Windows OS.
That is the behavior as why your that folder keep adding files after files.

Whatever you do, this will continue to have, unless you resolve it first.

Edit: Do note that the free edition of the SuperAntiSpyware is not an active.
As i run after surfing, but to update the latest malware, virus, etc, before Quick Scan.

It sounds like malware to me.
I would do as AddRAM suggested and re-install Windows.
