Wrong disk size


Something strange is going on with my pc and I can not see why. I have a ssd drive 220 Gb, supposedly only has 21 GB free. However when running FolderSize indicates to me that I have only occupied 150 gb.

best regards

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

This space is supposedly occupied by some protected files such as system snapshots or backup (if it is Lenovo machine).
Download a tool called Treeview or Windirstat and check the drive with it. Must be run as administrator as well.
Then you will see where the space is.
In System Properties disable shadow copies and remove old ones.

No, don't run it as admin, the admin account may not access all folders, run it as system account instead using psexec.

Psexec -s -i foldersize.exe

The system account will see all data.
