You normally can’t create a folder with the . character. One way to do it, though, is to add a . at the beginning and at the end of the folder name.
Another way to do it is to change the working directory to the C drive and then run this command:
“mkdir .well-known/pki-validation.”

The location needs to be an hidden directory, usually this is done by adding a dot in front of the folder name. Simply adding a dot in front of the folder name is not possible within Windows Server. There are two workarounds:
End with a dot
1. Create a new folder within the file structure of your (web)server and name it ".well-known.", do not forget the dot at the end.
2. The folder is now reachable via the internet.
Virtual Directory
1. Create a folder on the C-drive, name it “well-known”. In the recent created folder create another folder named pki-validation. Example:
C:\well-known\pki-validation
2. Place the text file in the “pki-validation” folder.
3. Open the IIS Manager on the server, right click on your site and select Add Virtual Directory....
4. In the Alias entry fill in “.well-known” and in the Psychical Path entry fill in the path to the Well Known folder. Example:
C:\well-known
5. End with OK, the folder and files within should work properly now.

• First, via command line, change the working directory to your c: drive:
• cd c:
• Second, staying on the command line, create the proper directory using something similar to the following:
• mkdir .well-known/pki-validation
I am assuming this is for a domain ownership verification challenge. To be clear, the general proper path for these kinds of challenges is the document root (wherever your website files live) which is typically not c:.
