You can of course use SystemExecute to copy a file to another location. You should, however, keep in mind the Clover is not "in charge" of copying the data - it just invoke a system command (in your case cp, pscp etc.). An example of why you should rather use File Operations components (e.g. CopyFile or MoveFiles) is described in this thread
Regarding the SystemExecute configuration you can refer to the documentation
. The most important (basic) attributes you need to set here is "System command" and "Working directory".
Hope it helps.
