I copied the largest of the files in System Volume Information into Everything and all it does is show the same information as TreeSize, except that it does show the time when the file was modified. Right clicking on the file name in Everything gives an option for Read Extended Information, but that did nothing.
I have also tried reducing the amount of disk space used for system protection to 157Gb and that has reduced the number of files in System Volume Information to 11 and File Explorer now shows 178Gb free.

That's like 30% of your drive size. Most times System Restore is 5-10%.

Why so much space?

Very odd that deleting restore points, leaving only 1, still leaves 6 files which look as if they are restore points. I wonder if there is a problem with Win 11 not deleting restore points when it should.

Download this and run it as admin, it should clean as much as possible.

I wish I knew.
You can limit the size to 320MB minimum or more, that should also remove any used space over the limit.
Code:
vssadmin Resize ShadowStorage /For=C: /On=C: /Maxsize=20GB

I stopped using System Restore years ago. System Restore has let me down way more times than it has helped me. An imaging program such as Macrium Reflect is more dependable.

As did I. SR has not been even reasonably dependable for me since Windows 7. In the years since WIndows 10 came out, not one time has system restore worked when I needed it, both on my own system , but others as well. I turned it off and reclaimed the disk space as I felt it was useless.

This. Not deleting, but turning it off completely. then reboot. Then see how much space you have left.

Don't worry for now about the comments regarding whether it works or not - obviously you have several hundred MBs of files, so yours is saving ... something. Once you have the space recovered, then let's target if you want to turn it back on, or go with something else. One step at a time.
