NZFF

There were two files in my FSX Addon Scenery\Scenery folder. One I have, which is NZMF_ADEX_VLC BGL the other NZMF bgl, I stupidly deleted in error.
Can someone tell me what the other bgl is as I may be able to pick it from the recycle bin?. Which is the best way to get it back. Do I have to reinstall VLC?. Thanks.
