Transferring projects back ONTO OT

I recently backed up my Octatrack (copied whole CF card onto my computer where it still sits now) and since then strange things have happened to one of my projects.

I’ve found a million threads about the importance of regular backups and how to do them, but I can’t find anything about how to then import things back ONTO the Octatrack.

I want to import the project I saved a few days ago, without obviously formatting my whole OT or jeopardising anything else that’s currently on there.

I can find said project within the backup folder, but is it as easy as just dragging that onto my OT while in USB mode or will bad things happen?

Can anyone enlighten me please?
