Link your Autodesk account, then sync your BIM 360 and ACC files directly from Mac Finder or Windows Explorer.
Sync is very efficient -- everything in the cloud first shows up as placeholder cloud files. Full file content is only downloaded on demand, so you save disk space and bandwidth.
You can also link other storage (such as Google Drive, Dropbox, OneDrive, and more) to odrive, giving you the ability to access everything in one place.
