Tell me about transferring files from OneDrive to a PC?

At work I often handle collaborative projects that are stored entirely in OneDrive, and sometimes I need to transfer full shared folders to my local machine so I can edit everything with offline apps. The trouble is that some folders are huge, and downloading them manually is slow and unreliable. I’m looking for a workflow that lets me sync or move everything efficiently, without downloading the same data twice or creating version conflicts.
