What are these folders?

Hi all

I've just clicked into the C: Drive of my laptop and there's load of files I don't recognise. The filenames consist of apparently random characters i.e. d6cff85c74a4d51b1edf7e3bb2f3fb and 6ec7d47c8b9ae18bd5d4c83cadd206. When I click into them there is a single notepad document with the following:

What are these?

They are files created by installing programs or updates and can be safely deleted.
