Win 8.1 - Where is my free space?

post #1 of 4
Thread Starter 
I run my Windows 8.1 off of my 256 GB SSD (C drive). I also have a 750 GB HDD for storage (D drive).

Windows is showing only 77 GB remaining on the SSD, out of the 238 GB partitioned.

This would be fine, if I had used up the remaining amount (238 - 77 = 161), but I can only account for 130 GB used up. This is including all hidden folders and files. I have NO idea where the remaining 31 GB is being eaten up, and I would like to find out and clean it up.

Any advice for where to start? I have run disk cleanup, and my computer regularly defrags I believe.

Need to use app like there is Baobab on linux,...it's disk usage analyser..

If you don't find it and you are familiar with linux you can use unetbootin to prepare bootable linux.

I used windirstat.

It found 25 GB that was unaccounted for.

(a) 6.4 are in hiberfil.sys

I am assuming this is a hibernate file? Seeing as I don't have hibernation enabled...is it safe to delete?

(b) 19 are in pagefile.sys

As I have 8 GB RAM i disabled the pagefile when I set up my computer. Apparently it set itself back up. I turned it off again.

Very helpful to look at it this way, thanks!

System files would be more safely deleted if backup is used. You can still use bootable Linux mentioned in second post to restore file if your system fails to boot.
