Windows 7 Why is there stuff inside SysVolInfo folder without previous SRP creation?

Much to my surprise I found some folders (e.g.

D:\System Volume Information\{d8216247-eb56-11e9-87e1-005056c00008}{3809876b-c176-4e48-b7ae-05046e6cc752}

....and 7 more similar folders inside the "System Volume Information" folder on my partition D:

This partition does not contain a running Win7/Win10 system.
Even more I never created a System Restore Point for this partition for my Win7 system..

So where do these folders come from?

Can I delete them?
