Did you know that you can run Leopard in tons of different languages? And not only leopard, most of your applications probably have a few language translations.
All this language support takes up space though. And more then a few megabytes. Getting rid of the language files you don't need could easily scrape 5gb off your hard drive.
So how do you choose the ones you want and get rid of the ones you need?
It can be done with a program called "Monolingual". It let's you choose the language files you want to use and get rid of the ones you don't.
Start by opening it up.
In the languages section check all the languages you aren't going to use and uncheck the ones you will.
Next simply click remove and your done!
You'll be amazed at how much space this saves.
