How to Unzip a JAR File

1. Download and install WinRAR (see Resources). This program is free to use for as long as you wish, thought some extra features are locked unless you buy the complete version. The free version is enough to decompress JAR.

2. Try out TurboZip (see Resources). This program is free to use for 20 days, but then you'll need to pay $50 to continue using it. The program has extra features such as the ability to preview files inside your JAR archive before you open it.

3. Use the program BitZipper (see Resources). This program is free to use for for a month before you'll need to buy the full version. Bitzipper lets you unlock multiple JAR archives at once.
