Thank you @pedro for sharing these to the community. I am clarifying about the change of behavior from 1.5 to 3.x to share more insight on this thread as well.
Many thanks for the follow up and apologies for not updating sooner.
As per our engineers, there was an issue before (even in 1.5.x) where PDF files did not have the “.pdf” extension added which resulted in issues opening the file locally. What we did to address issues like that was to append extensions to the files that didn’t have it based on their MIME types.
That makes no sense to me. If you use Google Drive on Linux you’re gonna have lots of files without extension, specially config files, like xyz/.git/sourcetree.
I’d like to put in the request of there being a way of disabling it, but in the meanwhile I’ve migrated to Dropbox.
If there are any news on this, feel free to ping me.
