How do i use my imported blender files

I downloaded this wolf on the blender website ,And i put it on a fbx.Then i put the folder in my unity assets folder ,But now i dont know how i can take out the model.

You should just be able to drag the model onto your scene. As in drag the imported FBX.

“Take out”, you mean “use in Unity”? If you created a “wolf.fbx” from within Blender and copied that into your Assets folder, it should appear in your “Project” view under the name “wolf”. Just drag it into your scene, or the Scene View.

I strongly recommend reading some tutorials about how to do basic stuff with Unity, for example some of these: How can I start learning Unity fast? ( List Of Tutorials ) - Unity Answers
