This works ! But unfortunately I don't understand how :-(

in thread Invoking the Windows command line for selected directories
Can't find anything coherent in the documentation of system and exec. perldoc just says:
If there is more than one argument in LIST, or if LIST is an array with more than one value, starts the program given by the first element of the list with arguments given by the rest of the list.
Although this only makes things less clear.
Where can I read the documentation about your solution ?
