Hi @clubwdw,
Can you take a look at this post and see if it answers your question? Do I need Premium to sync files on an on-going basis?
Basically, if your audio recordings are going somewhere on your computer that is outside of the odrive folder (e.g. C:\AudioRecordings) and you are using odrive to sync from C:\AudioRecordings\ directly to some location in Amazon Cloud Drive, then that is a premium feature (setting up a sync relationship from a location outside of your odrive folder directly to Amazon Cloud Drive).
If you can have your audio recordings just place the output recording files directly into a folder location within your odrive folder (e.g. C:\Users\Me\odrive\Amazon Cloud Drive\Recordings), then that is how you can keep doing what you’re doing on the free plan. Or have some process periodically copy the recordings into the location in the odrive folder.
