"fa fa-link Alias 
The alias remote provides a new name for another remote.
Paths may be as deep as required or a local path, e.g. remote:directory/subdirectory or /directory/subdirectory.
During the initial setup with rclone config you will specify the target remote. The target remote can either be a local path or another remote.
Subfolders can be used in target remote. Assume an alias remote named backup with the target mydrive:private/backup. Invoking rclone mkdir backup:desktop is exactly the same as invoking rclone mkdir mydrive:private/backup/desktop.
There will be no special handling of paths containing .. segments. Invoking rclone mkdir backup:../desktop is exactly the same as invoking rclone mkdir mydrive:private/backup/../desktop. The empty path is not allowed as a remote. To alias the current directory use . instead.
The target remote can also be a connection string. This can be used to modify the config of a remote for different uses, e.g. the alias myDriveTrash with the target remote myDrive,trashed_only: can be used to only show the trashed files in myDrive.
