Director does a lot of things well, but Xtras really enhance its ability to deal with external files. These are just some of the Xtras available that will open external applications, copy files, create folders, kill and manage processes, read and write to the Windows Registry and INI files, and much, much more.

Start with the free Xtras: FileIO, which is included with all versions of Director, and FileXtra (http://www.littleplanet.com/kent/kent.html), which is freeware and also ships with D6.5.

Sells Xtras that control external applications:
zLaunch (Mac and Windows) launches and waits for external applications in low-memory situations and also covers the desktop.
zOpen/zPrint (Windows) locates the application associated with an external document and uses it to open or print that document.
zScript (Macintosh) adds ability to send and receive AppleEvents to and from Director via AppleScript.
