Deleting Materials linked to hundreds of objects?

I loaded up a file that has almost 100 objects in it. They are linked to 10 different materials.
I would like to delete these 10 materials.
Is there an easy way to do this?
For some reason, the only thing I can think of requires me to go object to object and click that X button on the material.
Then… save the file, quit Blender and re-load it to flush out all these unlinked materials.
Sigh… please tell me there’s another way.
Please?

try this,

select one object, delete all the materials then create a default material and assign it. now select all the other objects, right click the new grey object to make it the acive object and press ctrl L for the make links menu and select materials. now you should only have the one material to deal with when it comes to texturing your objects

Press on the X button of the material but with shift-key pressed. Just hovering over the button gives the following text: “Unlink Datablock (Shift + Click to set users to zero, data will then not be saved)”.
Then just save and reload the file, the material is gone.

Nice tip Markus, didn’t know this!
