command execution

Greetings,
This does not work, can you help?

“robocopy \server\deadline_addons\ C:\ /COPYALL /s /e”
i send this command via: remote control\command execute

the return message is:
Failure: Failed to spawn process “robocopy” with “\server\deadline_addons\ C:\ /COPYALL /s /e” arguments because: The system cannot find the file specified (System.ComponentModel.Win32Exception) (System.Exception)

even
“copy m:\text.txt c:” does not work, guess i am asking for “so easy?”

this works:

cmd /C start “robocopy” “\server\BFD\TEMP\Robocopy.exe” \server\deadline_addons\ C:\ /COPYALL /s /e

actually this is working:

cmd /C start “robocopy” “\server\BFD\TEMP\Robocopy.exe” \server\deadline_addons\ C:\ /COPYALL /s /e /w:1 /r:1 (this makes it skip files in use)

found my mistake through some posts here…
