 // check for the existence of the path, so if it is passed a directory
 // without the trailing \, it will interpret the last component of the
 // path as a file and chomp it. This does not support relative paths.
 // Examples:
 // path == "C:\pics\jojo.jpg",     returns "C:\pics"
 // path == "C:\Windows\system32\", returns "C:\Windows\system32"
 // path == "C:\Windows\system32",  returns "C:\Windows"
