Blender 4.0 mostly opens older Blend files directly (File > Open). For very old files or unsupported formats, try: Intermediary version: Open the file in a closer Blender version, save it, then import into 4.0. Supported formats: Use File > Import for common formats like OBJ or FBX (data loss possible). Add-ons: Search for community-made add-ons for less common formats. Remember, major version changes may cause minor translation issues. Consider exporting to a neutral format before making big changes in 4.0 for easier import back to older versions.
