I have a Mathematica file in my Google drive. There is no option to open the Mathematica file directly, without downloading it.
Is it possible to directly open the file from Google drive?
If you have a public link, you can follow the answer to this question, and basically just import the data
If you need to authenticate to get a private link, then you will need this answer and the packlet by @b3m2a1
PacletInstall[ "ServiceConnection_GoogleDrive", "Site" -> "http://www.wolframcloud.com/objects/b3m2a1.paclets/PacletServer" ]; gd = ServiceConnect["GoogleDrive"]
