What is the IndentityCRL Public Folder

I am currently investigating sharing of folders and came across the instance of a folder named Microsoft>IndentityCTRL.

Is this alright to have running in the background as a folder and what are the properties of it?

See this: Microsoft - IdentityCRL folder - Microsoft Community

Very interesting - thank you - looks like most people hide it.

I am surprised at the amount of people that have the same issues. I do not feel alone.

I am currently in the process of control who shares the documents as I am very confused by the networking of three computers on a workgroup

Thank you for your assistance.

I may leave it there as deleting it may corrupt something as well.
