One way to access the content of a .max file is to use Autodesk's free online viewer, which allows you to upload and view .max files without the need for the software itself. Additionally, there are third-party websites that offer online conversion tools for .max files, allowing you to view and download 3D models curated in .max format. Whether you are a 3D artist, designer, or developer, being able to open .max files online can be immensely useful for accessing and sharing 3D models created in Autodesk 3ds Max.
