When I start the game and put in German, created in me in the long folder but no de_de.json. Any help?
Open the ".minecraft" directory
Go to the "assets / indexes" folder
Open the file with the name of the game version you are using
Search the file for "de_de" for the German-language language file
Take the first two characters of the associated hash code
Go back one folder and open the folder "objects" there you search for a folder with the two beginning signs.
Now only for a file with the name of the entire hash code from the file of point 4.
You are glad that you have found the file.
thanks!
