Hello there, Blender friends!
When I viewed a .blend file this evening I noticed that it is packed. As you can see on the image below, you can’t select any of the menus (3D-view, IPO-Editor,… for example).
When you “mouseover” this Box next to help, it says: “Indicates this is a packed file. See file menu”
I searched the entire Web and I am hoping for your help now, because I want to do that with various of my files, too, that I want to defend from external changes. But I don’t know how it works.
