BLZ Extractor is a tool for retrieving the contents of the Nokia N-Gage game containers (files with 'BLZ' extension). Since these games run not only on N-Gage, but also on other Symbian-based smartphones, they are very popular, keep in mind, however, that you must legally own the game for which you want to use a corresponding blz file. So if you have a Nokia 6630, for example, and want to play a N-Gage game through the blz file (this is the only way in most cases), you must buy the game anyway. But not all that good, installation of these games with the default installer (which you have to run on the phone) is not as fast as you probably want it to be, you have to transfer blz file to the phone (and this is a slow process, especially if you use bluetooth) then you run installer on the device and finally it unpacks the game (this is slow too, because phone in comparison with PC is a very slow device). What's more, all of this requires you to have enough of the available phone memory to hold both blz file and unpacked game data. With BLZ Extractor you just need to unpack the game on your PC and transfer resulting files (these usually consist of one folder named 'System', which contains all other files) to the phone (to disk 'E' on the device). That's all, fast and without excessive use of phone memory.
