Windows 7: System drive is full. why?

System drive is full. why?

Hi All

I am new to this form and hope this is the right place to get help.
My C: dreive is a 128GB SSD which devided into 70 and 50 GB logical drives.
Windows and all programs are installed on 70GB, the 50GB drive is free.
All programs are about 11GB, Win7 ultimate 64 is about 17GB so all together it should not exceed 30GB. Suddenly I found on one day that my user folder became 25GB without any reason. When looking into it and calculated all subfolders it even did not come to 1GB.
So the C drive is almost full and I have no idea for the reason.
Can anyone help?

Welcome to Seven Forums bigbingo. Do you have Hibernate turned on? The hyberfile.sys file can grow quite large.

Hibernate - Enable or Disable

In addition to Tree Size, I like the free Space Sniffer

System drive reading more full than it should be
Hello all, I recently noticed that my 1TB system drive only had 331gb free space on it, but I can not locate what is using up so much space. If I check the properties of all the folders on the drive it only adds up to around 200gigs. Any idea where the extra 400 gigs could be coming from? ...
