Moves the contents of the source directory to the destination
directory. Rclone will error if the source and destination overlap and
the remote does not support a server-side directory move operation.

To move single files, use the [moveto](/commands/rclone_moveto/)
command instead.

If no filters are in use and if possible this will server-side move
|source:path| into |dest:path|. After this |source:path| will no
longer exist.

Otherwise for each file in |source:path| selected by the filters (if
any) this will move it into |dest:path|.  If possible a server-side
move will be used, otherwise it will copy it (server-side if possible)
into |dest:path| then delete the original (if no errors on copy) in
|source:path|.

If you want to delete empty source directories after move, use the
|--delete-empty-src-dirs| flag.

See the [--no-traverse](/docs/#no-traverse) option for controlling
whether rclone lists the destination directory or not.  Supplying this
option when moving a small number of files into a large destination
can speed transfers up greatly.

Rclone will sync the modification times of files and directories if
the backend supports it. If metadata syncing is required then use the
|--metadata| flag.

Note that the modification time and metadata for the root directory
will **not** be synced. See https://github.com/rclone/rclone/issues/7652
for more info.

**Important**: Since this can cause data loss, test first with the
|--dry-run| or the |--interactive|/|-i| flag.

**Note**: Use the |-P|/|--progress| flag to view real-time transfer statistics.
