Free space on system drive

[AIsupport]

Last month i've periodically receive messages about "not enough space on disk C:\"
Have cleaned up most of it, but still didnt get one thing

As you can see here - total capacity of disk is 48,7 Gb. Hidden and system files are shown. Total weight of all disk content is 35,6 Gb (including hiberfil and yes, no pagefile on C:\). Currently I've got only 350 Mb of free space. Question - where is my free 13 Gb?

Use TreeSize free to see if it shows where the missing 13 GB space is used.

If you want the portable version, select the Zipped Executable from the download dropdown list.

It was System Volume Information. After deleting old recovery points I've got my lost 13 GB.

System Volume Information holds the System Restore points, you may have none left. Might check SR didn't get turned off and see if a full shutdown then restart makes a new point for today. Read this:

I know this. I setup it to hold only one last restore point. It's maximized to 4 GB.

If you use Avast AV, that has a bug and is known to change the max space used for some people.
