As Windows now document the OneDrive placeholder engine that they are using Windows Projected File System (ProjFS), which is built-in of Windows, I wonder if oDrive would consider somewhat create a new agent using this engine as it would also support command line access instead of just Explorer from current engine.
We have looked at ProjFS, but don’t have plans to utilize it, at this time.
We do offer the odrive CLI, which provides a command line interface to the Windows odrive engine. We also have odrive agent, which is used exclusively by the CLI. Have you taken a look at it?
