What is a .aois file?

The .aois file extension is typically associated with Autodesk Alias, a professional 3D modeling software used in automotive design and other industrial applications. This format is essentially a container for image data, likely specific to the rendering or preview capabilities within Alias. It's not a general-purpose image format like JPEG or PNG, meaning it's primarily intended for internal use by the software it belongs to. Files with this extension might store textures, rendered views, or other graphical elements crucial for the design workflow in Alias.
