A "dir" command executed in a specific folder (working folder) with the output redirected. A dump output stream is not used any more because in this case we know the command will dump everything to a file.
executor.exec("dir >> list.txt", new File("c:\\Users\\Public\\Pictures\\Sample Pictures"));
A file with the output of the command will be created:
c:\Users\Public\Pictures\Sample Pictures\list.txt
