Textfile in none-english installation

[Ursidey]

Hello,
Until now i installed the game and the mod in english, the textfile was in englishpatch201.big in lang folder. I made my french translation and i put the textfile in this .big, the mod was in french 

Now I have installed the game in french and the mod in english, but when i put my french lotr.str in the same englishpatch201.big in lang folder, the mod is still in english.

The lotr.str used by the Edain Mod doesn't seem to be in englishpatch201.big anymore : ?? I don't find it
