I have create a repository on my laptop, how can I clone the repository in my laptop to my desktop? I have already created a shared folder where my repository is located. Thanks in advance.
"Shared folder" suggests that you're using Windows.
If your shared folder is available as a mapped network drive, say
z:, then you can just clone as if it were a local repository:
git clone file://z:/path/to/repository.git
(I'm not sure about slashes vs. backslashes here; currently on Linux so I can't test it.)
Your question title asks about pulling, not cloning. But pulling should be trivial once you've got the clone.
