Regex to validate a valid Windows folder/directory path?

Question

I need a regex to be used in windows application for valid FOLDER paths only.
I am using Javascript for this and I've been normally a developer on a MacOS machine. So I need some help here.

I have a based regex which you can test here => https://regex101.com/r/qLdxZM/1
As you see on that link, it is accepting things like => C:\Projects\apilibrary\apilibrary.sln which is a file path and not a folder path. That should not be accepted.
So I need to modify that regex to accept only local valid Windows folder paths.

The regex to be modified is => /^[a-zA-Z]:\(((?![<>:"/\|?]).)+((?<![ .])\)?)$/gm

Help me in this, please.

Thanks in advance.
