Firstly, why would you want to? The power of git allows you to work with multiple branches within the same path.
If you need the repo in another location, just clone the repository at that path:
C:\some folder\misc\builds> git clone http://pathToMyRepo.git
Then switch to the branch you want:
C:\some folder\misc\builds> cd \MyRepo
C:\some folder\misc\builds\MyRepo> git checkout builds
