Export object WITH materials and then import it back

Support Basics & Interface

I have an object and want to export it from blender and then import it back to another scene i’m creating. But with every export extension I loose materials! How to solve that so materials won’t get lost in exportation?

Just use Shift+F1 to append from one blend file to another
