Missing 30-40Gb from SSD?

Hello, I'm running low on space on my SSD (20gb left apparently), so I decided to tally up what I have and see what I can drop. I quickly noticed that it wasn't adding up - with hidden folders, I'm using using about 42gb of my 110 gb ssd (103 gb in actuality). Looking into it some more, I checked things like shadowstorage, but only 1Gb is allocated to that. So there's still ~35 GB missing. Anything I can do to fix this? I found this System Protection - Change Disk Space Usage already and that didn't help.

Thanks!

Run Treesize Free. It will show you where the disk space if being used. Make sure Folder Options, View, Show hidden files, folders and drives is selected.

Thank you for that program. The missing 30gb is in Windows. Is there any way to cut this down a bit without breaking anything?

For starters you can get rid of the hiberfile. The command is powercfg -h off. Then you can reduce the pagefile to 2GB. Then you have to tell us what other BIG files you have.

You should also check the shadowstorage. The command is: vssadmin list shadowstorage

My 60GB SSD with a 4 year old windows 7 and a gezillion programs has 25GB of free space.

The other big files are:
-winsxs at 11.4gb
-Installer at 7.7gb
-System 32 at 5 GB


The rest are all at or under 1 GB. Shadowstorage has only been allocated 1 GB with a max of 1.5GB. getting rid of hiberfile did help, thanks :)

You could try running Disk Cleanup from the start search box and say yes when it asks you if you want to clean system files.

Try using WizTree free, i think it's better at finding "missing space".
They have a portable zip download available, no install needed.
