Fawzia Mod Verifier
Download: http://www.mbrepository.com/file.php?id=1986
A simple, powerful tool that checks your mod's meshes, textures, music and sound files, and your items. It reports missing and unused files by cross-checking the contents of your mod *.txts and *.brfs with the files in the Music, Sounds and Textures folders. It also reports problems with your items.
It works best in conjunction with the excellent OpenBRF:

If you have a file missing, it may be because of a spelling error, either in the code on in the filename. If not, find it and add it to your mod, or remove references in the code.
If a file is reported unused, you can delete it (back it up first). Cut that download size!
It works both for Mount and Blade and Warband. Tested on many different mods, and, not surprisingly, all of them had some errors or unused files lying around. Even Native has some missing sounds and duplicate item IDs (Warband Native).
To install:
1. Unzip to some folder
2. Remove a previous FMV version, if you have one
3. Run setup.exe
4. Wait for the MS Net Client to download and install, if you don't have it already
5. Once installed, it will automatically start
You can find it later in Program Files->Mad Vader HQ. If you want to remove it, go to Control Panel, Add/Remove Programs and find FawziaModVerifier.
Note: it's called Fawzia Mod Verifier, because it was made for Fawzia's use during POP 3 development.
Have fun,
MadVader
