.JDIS File Extension

A JDIS file is a .DFM (Delphi Form) file that can be used to create an Inno Setup script (.ISS file). It contains configuration details used to generate a script. JDIS files are created and can be opened by JD Inno Setup Configurator.

ISS files are scripts used by Jrsoftware Inno Setup, a free program that developers use to create Windows installers. Typically, developers create and edit ISS files using the Inno Setup Compiler. However, Delphi developers can use JD Inno Setup Configurator, a free program developed by Jerry Dodge, to create ISS scripts within a GUI.

JD Inno Setup Configurator saves developers' in-progress Inno Setup script projects in JDIS files. JDIS files are Delphi Form files that have been saved with a custom extension, for use in JD Inno Setup Configurator.

You can open a JDIS file in JD Inno Setup Configurator (Windows). To do so, open the program and select File → Open....
