How to convert NEF files to .jpeg

Help! Somehow during the process of trasferring pics from my D90 Nikon to the computer they transferred as NEF files, and now even when I move the files to another folder I can't seem to download from the camera, and I don't know how to convert the files from the NEF to JPEG format.

Any ideas?

 

=====================================
Nikon NEF files are what are commonly called RAW files.
If you prefer to download your photos in the JPG format...
you can make a setting change in the camera.

You can download a .pdf copy of the manual for your D90
from the following link:
http://support.nikonusa.com/app/answers/detail/a_id/16087/~/user's-manual---d90---guide-to-digital-photography
(just right click "Download the D90 User's Manual" and
choose...Save target As.  It includes info on NEF (RAW) files)

Maybe the following links would be worth a look:

(FWIW...it's always a good idea to create a System
Restore point before installing software or updates)

FWIW...there are some 3rd party retail
alternatives that may be worth looking into...
