This is unfortunately not as simple as just creating a Zip2Go and changing the extension type to .mcam-content, as strange as that my be. Believe me, I've tried it and customers can't load the file. I believe that is because zip2go creates folder structures with versions, ie “Shared Mastercam2021.” To get the content file to work, though, you need to strip the version info. In this example, it should be “Shared Mastercam” instead.

Here is the link to the knowledgebase info on how to create a .mcam-content file: https://kb.mastercam.com/KnowledgebaseArticle50652.aspx?Keywords=make+a+content+file

TL;DR, Mastercam suggests creating a folder on your desktop that has the Shared MCAM structure, but notice there is no version info. PY files look like too if you investigate their structure.

So far I've done it the way CNC suggested, which is the only way to do it with 2020 and prior. But starting 2021, you should be able to create a z2g and go in and modify the folder names. Here is how that would work:

Open Zip2go > hit Create Zip to Go > –optionally name the .mcam file if prompted– > Change file type to .mcam-content > create zip2go as normal

Now find the new .mcam-content file and open it up. Modify the name of the “Shared Mastercam” folder inside so there are no versions. This should be it.
