Hi @edgar,
I may be misunderstanding, but if you are looking for auto syncing, you already get that in the free version of odrive.
Take a look at this post for lots of details on Free and Premium, including sync specifics: What is free vs paid (premium)?
Anything you save into the odrive folder will be uploaded up automatically. Is this what you are wanting to do, or is there a different use case?
Is the issue automatic download of files?
