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 package contents of applications you have installed on your Mac. You can find them if you open the Resources folder and 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 Skype.
In most cases, you can trash the folders and files for languages you don’t know or don’t speak. Note, that for every application you should manually find and select these files for removal. But there’s an alternative way...
How to delete additional language files automatically?
Instead of trashing language files manually for every single application, you can take advantage of CleanMyMac 2.
As a user, you are only required to hit Scan after you’ve launched the app.
When the scan is over, click Clean. This will clean up your Mac from various system and application junk including unwanted language files.
Alternatively, you can proceed to the System cleanup module, click Detailed Results and uncheck everything except Language Files.
Moreover, you can manually edit the list of languages you want to be excluded from your system.
After you have done it, click Clean then to exclusively delete language packs for more space on a Mac.
