SQL 2012 :: SET CMD Value Based On Select Name

I am trying to move files to directories based on the file status. If the file contains the Flag='E' then I want to move it to an "Error" folder, otherwise it will go to a "Processed" folder.

Here is my current code:

DECLARE @cmd varchar(500)
SELECT
CASE
WHEN Processed_Flag = 'E'
THEN
SET @cmd='MOVE /Y C: empmyfiles*.dat C: empmyfilesError'
ELSE
SET @cmd='MOVE /Y C: empmyfiles*.dat C: empmyfilesProcessed'
END
FROM#TEMP

PRINT @Cmd
