is there any easier way to share files or should i just spend a few days learning abbout GIT. Thanks!
Just gonna echo what everyone else has said.
If you're willing to learn to develop games, then you can definitely learn GIT. Another way to put it is, if you find GIT difficult to learn, then you are going to have much more difficulty with gamedev in general. So might as well learn it, it's a very powerful tool!
It's not too difficult, relatively speaking. An hour or two of trying it out should get you there. That said, you need to put in a little bit of effort to learn and dive into what source control is and how it manages your projects. That's that's just the thing for gamedev. It's easier than it's ever been, but still requires some effort.
I would also recommend an external client like github desktop instead of GMS2's built-in plugin. As you'll be able to back up any file you want, not just what GMS uses.
Watch some videos to help you decide.
