Design Library File Changes Type when renamed

Hello All---

I renamed a part using the design library interface in solidworks.  After I completed renaming the part, I could no longer find it through the solidworks interface.  After finding it in C:\ProgramData\SolidWorks\SolidWorks 2012\design library\routing\piping\pipes directory I found that the file had the new name I gave it, but it was not a solidworks part.  I have attached a screen shot.  Does anyone have any ideas how to fix this?  Is there a way to rename parts in the design library window in the solidworks interface or do I need to find the actual file on my C drive and change the name?

Thanks.

Sincerely,

Chris
