Locate the language files folder for the application. You can also search for the language files, such as Japanese.Iproj or ru.iproj. The former tells you the language used, but the latter might need another helper.

Part 3: How to Remove Unused Language Files from Mac via Terminal

When you want to delete the file on a Mac, you will need to disable SIP, or System Integrity Protection, which prevents accidental modifications to certain local files. To avoid disabling SIP, you can use Terminal. The Terminal is Mac's command-line interface, which allows you to directly execute different types of processes and tasks.

Step 1:

Go to the Applications folder, click the Utilities app and select the Terminal option. After that, you can input the following command:
sudo find / \( -name *.lproj -and \! \( -name English.lproj -or -name en.lproj -or -name en_AU.lproj -or -name en_CA.lproj -or -name en_GB.lproj \) \) -exec rm -rf {} \;

Step 2:

If you want to delete foreign language files, you can add -name en_AU.lproj -or within the \(\) command and replace en_AU.lproj with the language file to be removed. Remember to copy and paste instead of typing it, otherwise, you might make mistake and break something.
