Does Rclone Mount make local copy of all the files in Bucket

Does Rclone mount copy each files locally from bucket or just creates a network share like link to actual cloud location?
Need this details so as to plan for disk storage utilization once Rclone mount is setup.

I think you will find all answers in mount documentation especially part related to VFS.

If you need more help I suggest you explain what your requirement is then somebody can have some suggestions how to achieve it.
