Unity supports many types of asset files via its collection of built-in importers. Most of these are “Native importers”, and provide the import functionality for most of Unity’s basic Asset types such as 3D models, Textures and audio files.

Scripted importers allow you to write your own custom importers for formats that Unity does not natively support. However, in addition to the built-in native importers listed above, some of Unity’s own built-in importers are themselves implemented as Scripted Importers. This is because they are implemented in C# in core packages, rather than within the Editor’s native code itself. This means Unity will always import these types of assets after native importer assets.
