Each SFTP user can be mapped to a whole bucket or to a bucket virtual folder. Mapping a virtual folder is very similar to a chroot directory for the local filesystem: you can expose different virtual folders of the same bucket to different SFTP users. Each SFTP user can only access to the assigned virtual folder and to its contents.
