The windows command shell does have full support for files and folders with whitespace in them (e.g. Documents and Settings), you just have to quote them properly.

You'll have to iterate over each element of the array and add it (preceded by a space) to the command line. Or use the exec() signature that takes an array of strings. You'll still have to ...
