Most applications on a Mac translate (or localize) their interface to dozens of regions and languages. Usually, individual language files do not take up much space, but depending on the number of your apps, all localizations combined may consume a lot of disk space.

You can safely delete unneeded language files on your Mac. Read the article to learn the two ways to clear unneeded language files.

What are Language Resources

Language Resources are special localization files of software that make interface languages available in a program. Some programs have a huge number of possible interface languages that are worth considering. But usually, users need only one version of the interface or just a few – obviously not twenty.

How to delete language files on a Mac manually

Language files of applications are stored within the apps, so you can go inside your apps and remove unneeded language files.

Follow these steps to find and remove language resources:

  1. Open Finder and go to the Applications folder.
  2. Find the app which provides numerous localizations for their interface.
  3. Right-click on the app and select Show Package Content from the context menu.delete language files mac
  4. Next, you need to find the folder with localization files. Often language files have names such as Japanese.lproj or ru.iproj. While in the first case, it is clear what language is used, in the second case – you may need some help. Here is a small table of the most common language codes:how to clear language files on mac
  5. Select unnecessary language files and remove them.
  6. You should do steps 2-5 again for every app you want to clear from the unneeded translations.
Please make sure you didn’t select for removal the languages you need. Otherwise, you may miss out on the interface language. Also, you should not remove the Base.lproj folder and English localization files because elsewhere your app might not work.

Please note, the app doesn’t remove language resources from the default Apple applications due to System Integrity Protection (SIP). Also, by default, MacCleaner Pro does not mark the languages you use, i.e. those which are available in your keyboard preferences. And, finally, MacCleaner Pro does not allow you to remove English localization because it’s usually the default language for apps and is critical for their usage.
As you can see, clearing language files with MacCleaner Pro is super easy. Use the app’s other tools to clean and speed up your Mac.
