Problems with the use of Robocopy

To copy a file from one directory to another I use this command line

C:\>robocopy %userprofile%\desktop\db_doctor.sql D:\hi  /E /MT:24 /MIR

And this is the error that commands when executing:

  

2017/05/25 11:05:26 ERROR 123 (0x0000007B) Gaining access to the   source directory C: \ Users \ Byron \ desktop \ db_doctor.sql \ The name   of file, the directory name or the syntax of the label d   olumen are not correct.
