How to export/import Inspector information?

I want to know how to export Inspector information to file and how to import Information to Inspector from the file? Because I set some Information in the Inspector (like the textures and texture positions) and these Info bind in models in the stage.if I modify the models I will lose these info. So I should be spend more time to set these Info again. Does the Unity3d 3.0 provide these export/import functions in it? I don't want to write some programs to save these info.I hope Unity3d can provide like thse functions in it.
