To differentiate between a folders default/physical name and it's localized representation for display purposes, the following method is introduced in the interface com.openexchange.file.storage.FileStorageFolder:

/**
* Gets the locale-sensitive display name of folder.
*
* @param locale The locale
* @return The localized name, or <code>null</code> if not available
*/
String getLocalizedName(Locale locale);

The default implementation in com.openexchange.file.storage.DefaultFileStorageFo lder just returns null and may be overridden by concrete implemantations as needed.
