This is how to delete useless languages on your Mac

What are language files?

Almost every application on your Mac is available in more than a dozen languages and thus contains specific language files, for that matter. Since you don’t speak most of these languages, such files just waste space on your Mac and can be safely removed.

How to clear out unnecessary language files manually

Language files are kept in the package contents of applications you have installed on your Mac. Here's how to find them:

1. Open Finder and go to Applications.
2. Right-click the app and click Show Package Contents.

   

3. You'll see the Contents folder — open it.

In the Resources folder, you'll find folders ending with “.lproj”. Every folder contains language files for one particular language and thus has a name of this language or its shortening. For instance, here are the language files of Google Chrome.

In most cases, you can trash the folders and files for languages you don't know or don't speak. Note that you should manually find and select these files for removal for every application. But, we know a way that's a bit easier.…
