Is it possible to add a folder of documents that become a sub-domain to my main site. e.g. newfolder/mydomain.com?
No, not as you describe.
However, if you want two different sites with different content in different folders on different subdomains, that is possible.
May I ask more abstractly, what are you trying to achieve? If you want to separate different types on content on a single site, then perhaps tagging that content might work?
