Enclosing the source or destination in double quotes allows the use of paths with spaces in the folder names but DO NOT end with a trailing backslash ‘\’ as this will be interpreted as an escape character.
When using the task scheduler to run a robocopy command script be aware that using the account credentials of the logged-in user may be necessary for access to network drives referred to by the command. An administrator account may not have the necessary permissions.
Syntax
ROBOCOPY Source_folder Destination_folder [files_to_copy] [options]
ROBOCOPY "M:\" "X:Destination Folder\" DON'T USE EITHER OF THESE
