What is an XSI file?
An .XSI file typically stores 3D models, animations, and scene data. The format is primarily known as a Softimage XSI 3D Image or 3D scene file, originally created by Softimage and later acquired by Autodesk. These files hold geometry, lighting, materials, and rigging data used in 3D animation and visual effects.
In some cases, an .XSI file might be a generic XML-based data file used by various software applications to store structured text data. Because the extension is used for different data types, identifying the correct format is important.
How to open XSI files?
To natively open a 3D .XSI file, you usually need specialized 3D software. Autodesk Softimage is the original software but is no longer officially supported. Other 3D tools like Autodesk Maya or Blender can open these files using conversion plugins. If the file is a generic XML data file, you can open it with a simple text editor like Notepad++ or Visual Studio Code.
