[QUESTION] Repacking Large MPQs

[T25755V]

I'm trying to create a model edit with a large number of files. I have the files extracted, and the directory structure intact. Essentially, it's all organized and ready to be recombined. My question, though, is how I can repack all of the files into an MPQ without having to import them into a file one-by-one in MyWarcraftStudio.

Any ideas? I've tried using MPQeditor, but I don't think I did it right; no models changed when I put it into WoW.

Be sure to name it something like patch-b.MPQ not patch-b.mpq. The MPQ needs to be capitalised otherwise it wont load. And packing with MPQEditor is easy. Thats how I pack mine.

I have the naming convention correct. Are there any settings in MPQEditor I should know of?

As a note, when I open the packed MPQ in MyWarcraftStudio, it doesn't show anything in it. The MPQ is 23MB, however.
