Can I safely delete these foldes?

After installing P3D v4.1 I have a need to clear some space on my C drive.  It's slowing down my computer and making it unusable for some applications,  including flight sim.    I've found lots of disk space on C occupied by unnecessary files that I'm deleting,  but I've found a bunch of folders with about 40GB or so of files with names like Scene4.cab.   They're in folders here:   

c:\program data\package cache\(C953A291-C0D5-414E-8211-778D5E53D73Ajv4.1.7.22841

 

Can I safely delete those?   They look like temporary files to me.  (And I admit I dont know if they are P3D files - they might well be from something else I've installed. )

Deleting them will break the ability to do a repair or uninstall.

Thank you Ed.

I found a post on a techo forum  that explained how to link another drive so it behaves like a folder on the C drive, so I might do that.     if so, I can move a whole lot of other stuff too.    Giving the C: a lot more space  and moving stuff to another SSD ought to speed things up quite a bit
