File search "pecking order"

Does anybody know what the SolidWorks file search "pecking order" is?

Say I open an assembly: c:/bubba/test.sldasm.

test.sldasm references two parts:

c:/bubba/part_a.sltprt

c:/bubba/part_b.sldprt.

Someone comes along and moves part_a.sldprt to another directory.  Before SolidWorks gives up and pops up a message, I *think* it tires to find it.

Where does SolidWorks then attempt to look for it next?  And if that turns up nothing, after that?

Thanks.
