Accidentally loaded too many materials libraries - now they're locked

[mblacklock730107]

Hello everyone - I accidentally loaded *all* of the physical materials libraries in Revit. For example, PhysicalMaterial_Structural_Germany, all of the other countries, please see attached. Now they are locked, and I can't remove them. Is there a setting I have overlooked that I can change that will allow me to remove them?

Thanks!

Melanie

Thank you, but I've already looked at those, and they didn't have an answer for me. The libraries' files are not marked Read-Only in the Windows folder. I'm a newbie, and loaded these extra libraries by mistake. They are all Autodesk libraries.
