# Localizations

OS X and many applications have been translated into a large number of languages, most of which are never used. Cocktail can automatically scan the computer and delete any languages that are not being used, freeing space by deleting hundreds, or thousands, of files from the disk.
To delete languages go to Files and select Localizations. Press Options to select the languages to delete and where Cocktail should search for localization files. Cocktail can scan the following three folders:

- /Applications
  Removes localizations from installed applications.
- /Library
  Deletes localizations for screen savers, preference panes, Internet plug-ins and helper applications.
- /System
  Removes localizations for OS X.

Selecting a language means that all dialects and variants belonging to this group will also be deleted. For example, selecting Portuguese will also delete Brazilian Portuguese. This applies to most languages so be careful when deleting languages such as Chinese, Arabic and Spanish.
Note that English cannot be deleted, as OS X requires this language to function correctly.
The first scan can take a while to complete (on some configurations the process can take several hours); following this scans should be much faster. It is recommended that you delete localization files regularly as system and software updates tend to replace language files.
