Have you encountered a problem with a JSX file? Don’t you know which program opens a file with this extension? You will find all the information you need about working with a JSX file here. In the further part of this page we have added a list of programs that should open your JSX file. It is enough you choose a proper application for your operating system, download and install it.


The file extension JSX marks script files in the ExtendScript language, which is an extension of Javascript. It is an Adobe-specific language that can be used to write plug-ins for Adobe Creative Suite products such as Photoshop.
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.
Please note that ExtendScript has several additional Adobe-specific features that are not compatible with JavaScript. You should also know for which Adobe product a JSX file was written.

Programs which can open a JSX file

How to open a JSX file? Advice and guidance

Absolutely most often appearing reason that prevents you from opening the JSX file is the lack of a proper application to support it in your operating system. It is notably the first thing you need to address. When one of the programs to support a JSX file from the list is already installed, you can try to rerun the file. The system should display a message asking you to choose a primary application to support JSX files. At this point we are looking for disk space where the application was installed in and we can link it with a JSX file. Since then, our operating system will use the selected program to support all JSX files.

Other issues

Despite the described problem with JSX there may be many more problems. If the existing operations were not effective, get involved with the following matters:

- verify that the JSX file is not damaged and that it has been downloaded or copied in whole
- verify that the file has a file extension that has not been intentionally changed (for example, if it do not contain other information than its extension suggests)
- make sure again whether the JSX file type is linked in the operating system with a proper program
- make sure that the file is not infected with a virus and you have up to date software and drivers.
