What is a IST file?

 InstallShield is an application for creating Windows Installers (.MSI files) and installation packages based on InstallScript. Project templates created in this program are saved as .IST files. They contain a template with default settings, design elements, and code. IST files can also include custom scripts, default images, directory structures, and text. IST file templates provide you a base for a new installation project. It is enough for developers to have several templates to standardize installers across multiple projects. IST can be created only in Professional and Premiere version of InstallShield.
