Can I access my projects from multible PC's?

I have UE4 installed on my laptop, and I just installed it on my Desktop. On my laptop, I have multiple projects in my library. But after I downloaded and installed UE4 on my desktop, none of my projects are there…and yes I am signed in. So what is the issue, and how do I resolve this? Also, both computers are using version 4.7.6.

library is for local project, you must copy your project folder from desktop to your laptop if you want to use, if you want to use the same then shared that folder locally then you can access from you laptop, or set up any svn or source control.

something that MIGHT work is source control, not sure how to set it up.

I use bitbucket to hold most of my projects. They have detailed explanations on how to setup your repo, and using Source Tree(Sourcetree - A free Git & Mercurial client | Atlassian) as a git client makes it even easier. Although I prefer to use tortoise(TortoiseGit – Windows Shell Interface to Git)

Take a look at these two tutorials, they should get you up and running:
