Hi @mh12,
This video is a little older, but it provides a nice walkthrough of the basic functionality of odrive. It is geared toward Amazon Drive, but the functionality displayed pertains to all of your linked storage:
This section of our usage guide goes through the basics of sync: https://docs.odrive.com/docs/sync-your-odrive
For the most part, once you have linked your storage to odrive, you really just need to interact with the files like you normally would interact with your regular files and folders. The major difference is that odrive uses placeholder files to represent your cloud data, at first.
Double-clicking on a placeholder file will either download and open the file selected, or “expand” the cloud folder so that you can browse further into the structure.
Any files you add to a linked odrive folder will automatically upload to the remote storage.
