I don't use WMP. I found it too unreliable and at time scary as it would lose content.
Consider a safer system next time.
Just bought an external hard drive to lighten the load on my laptop and thought I'd tidy things up by moving all my MP3's (ripped to "My Music" folder using WMP) onto it. But when I opened WMP and looked in my Library all my tunes were missing! Panicking, I immediately moved them all back and like magic they started to appear again in my library! Is there any way I can get WMP to look in the external HD rather than the laptop's to organize and play my music files? Cheers!
