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.

It sounds like you're talking about materials and Unity shouldn't not override materials when reimporting the models.
