Files with curly braces taking up too much space

There are these files with filenames beginning and ending with curly braces taking up too much space in my SSD main OS drive. They are located in the 'C:\Windows' directory. Could somebody tell what these are, and if they are safe to delete? I suspect something bad (virus perhaps), but I don't know. There are other files like these, as shown in the screenshot below, but they don't take up as much space as these recent ones. Are they needed by the system? Are they from a bad program?

Right click some & choose Properties & check them out.
Provide screenshots of the Properties window details.

You could also right click some & choose to scan them with your antivirus program.
Or open the antivirus program & do a file scan on some of them.

OK here's the screenshot of the properties plus the contents of the file. I did scan it for viruses or malware patterns, but it turned out nothing.

Interesting.

One more request.
What does it show under the other tabs ?

Are you there ?
Did you get things figured out ?
