How can I tell that YUP patch has been applied

[sebsyOTF]

Hi folks,
Finally getting around to playing FNV and would like to play with the YUP patch as this seems to the best unofficial patch similar to the unofficial patch for Fallout 3. But, how do I know it has been applied to my game.When I click to pay the game and the little options window comes up, in my DATA FILES section I have the .esm's for the game, and the four DLC packs, plus the two YUP files (esm & esp). I have them all ticked, but how do I know that it is definitely applied to the game?
All I've done after downloading the YUP patch is open it in WinRar and move those two files to my steam apps>FNV>Data folder and that made them appear in the data files list where I ticked them.
I imagine this means the patch is applied correctly to my game but just wanted to know if there is a surefire way of confirming this?
Thanks :)

As long as it's load order is after the main game and dlcs and activaterd, it should be fine.

Though you want to make sure archive invalidation is set up properly, otherwise any fixed vanilla textures may not be used. Some mod managers can do this for you.

Nexus Mod Manager does that when it installs.... The file invalidation ini line and the archiving

I haven't used Nexus Mod Manager, I just downloaded the file manually and then moved the files to my game folder and as I say they are in the Data Files list when you click to play the game.
