What is an IS file?

IS files mostly belong to Inno Setup. Usage of IS Files:

Installer Script: These files work as scripts for software installers. They are saved in UTF-16 (LE) and include commands that Inno Setup uses to control an installation.

Image/Game Script: Some IS files function as an image format linked to Adobe ImageReady or as script files for game engines like the Infinity Engine.

How to Open and View:
FilExt.com tip: If the file is an installer script, open it with any text editor (for example, Notepad or Notepad++) ensuring the encoding is set to UTF-16. For image or game-related IS files, use Adobe ImageReady or the proper game asset tool to view the content.

How to open an IS file

You need a suitable software like Inno Setup to open an IS file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your IS file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a IS file directly in the browser:. Just drag the file onto this browser window and drop it.
