Locating all texture files (PC)

[LostManAbroad]

So I found a map I like but all the signs in the map are in Spanish. So I decided to change them all in Gimp. I unpacked the zip file for the map and I opened each texture file containing Spanish writing and altered them. Once I was finished I went back into the game and noticed that there were a bunch of street signs that were not with the texture files I had altered and they all remained in Spanish.

I went back into the folder with the unpacked map and I carefully browsed through every single file contained within it and all the sub-folders. They simply do not exist so how are they in the map. I cannot figure out where they would be. Does anyone understand map creation well enough to help me figure out where all the textures I am looking for could be hidden? They have to be there somewhere, I mean they appear in the game when I load the map so there has to be corresponding files.

If you are familiar with GE you could export the sign, with files. Then check the path to the texture.

I'll have to try this as I simply cannot locate the textures for a lot of the signs.
