dtutil and spaces in package names

I'm having trouble running a statement like this:

dtutil /DTS MSDB/Budget/BUD_Production - dtsChart of Accounts Budget - Final /En FILE;BUD_Production - dtsChart of Accounts Budget - Final.dtsx;4

I've tried:

dtutil /DTS "MSDB/Budget/BUD_Production - dtsChart of Accounts Budget - Final" /En FILE;"BUD_Production - dtsChart of Accounts Budget - Final.dtsx";4

dtutil /DTS "MSDB/Budget/BUD_Production - dtsChart of Accounts Budget - Final" /En "FILE;BUD_Production - dtsChart of Accounts Budget - Final.dtsx;4"

Any suggestions?  I'm no DOS pro, but I can normally get things going.

Thanks

Sam
