This plugin mimics the "open selected file" in PSPad.
I am a PHP developer and i often see an 'require_once("../this/is/some/file.php");'. In pspad you can select the whole path (../this/is/some/file.php) and open it from the menu.
Now you can do the same in notepad++. Just select the whole path and press alt+o, or use the button in the toolbar on top.
