More info

JSX files are simple text files that can be opened and edited with any text editor. For development, Adobe offers the ExtendScript Toolkit for free download. Self-developed or downloaded JSX files should be stored under 'Preferences / Scripts', (if not available, simply create them) so that the program (eg Photoshop) finds them. After restarting the program, the scripts should be accessible via 'File -> Scripts'.

In the newer versions of the Adobe products (CS3 and higher) you can also use 'File-> Scripts' to 'browse' to select a JSX file. The procedure may be different for some Adobe products.
