|I did some looking around Microsoft's websites and other tech websites and couldn't find an answer.|
I have a total of 17 files in that folder: 9 text & 8 html, 62.8 MB total file size, all related to versions of the .Net Framework. If you're unaware, a framework is like the building blocks of an application. Using this framework, software developers can create applications and save time because some of the tools are already created. Taking a look at these files on my computer, it appears they're just log files.
I tried cleaning up temporary files in the latest version CCleaner and then the built in Disk Cleanup utility (Start > Run: cleanmgr) and neither tool cleaned up that folder.
If disk space isn't an issue, I say just ignore them. If it is an issue or you're way too curious, create a System Restore point first, then delete the files inside (not the folder itself) to the Recycle Bin. If you don't notice any system problems after a couple weeks (including a Windows Update attempt), I'd think it's safe to permanently delete them.
Apologies if I don't respond to your reply immediately. I don't check this site daily, but you're welcome to PM me as a reminder.
