Cmd /c is from the help:
Starts a new instance of the Windows XP command interpreter
CMD [/A | /U] [/Q] [/D] [/E:ON | /E:OFF] [/F:ON | /F:OFF] [/V:ON | /V:OFF]
[[/S] [/C | /K] string]
/C Carries out the command specified by string and then terminates
/K Carries out the command specified by string but remains
You have to be aware when its needed and when it isn't. For instance I
usually use ShellExecute, and if the command has the .BAT on the end and the
windows assocation for running a .BAT extension is in place then it make the
association with CMD itself. Specifying CMD/C will remove any uncertainty.
Remember if you run such a command on Windows 9x or ME then you need to use
instead COMMAND/C
