you're allowed to install BSS on 3 computers (full paid license) belonging to you. Or just one for the free student license. So just copy the .bsdesing to your other computer and work from there. See https://bootstrapstudio.io/contact-us#licensing
You can save it in the cloud, or send it via email. But first, you need to install BSS on your computer.
I have 1 desktop computers and a laptop in both I use Windows 10 and Ubuntu well I start a project on one computer and I want to continue using it on the other. When I tried to copy the folder to another computer, he asked me to introduce the license again, hence the question how can I share a project.
Just in case anyone else is wondering how to do this:
The BSS app will need to be "installed", not copied, on all locations you want to work on it.<br />
Your project files are what you want to save in the cloud, or copy the project files to a flash drive each time to go back and forth.
