Strings Resource files are standard localization files used for iOS and OS X applications. A Strings Resource file consists of key-value pairs connected by an “=” sign. It looks similar to a Java Properties file, except that both keys and values are wrapped in double-quotes and that each key-value pair ends with a semicolon.
If you generate Strings Resource files using a 3rd party tool (e.g. genstrings), it is possible that you end up having files with duplicate key strings. Generally, duplicate keys would not break the app, but it is always a good idea to remove these duplicates before initiating the translation process.
