Then go to %appdata% and then .minecraft and then to the folder.
server-resource-packs and then you will see a lot of numbers and letters then name the file eg test.jar and after that go to the website. http://www.javadecompilers.com/ and upload the test.jar and select Fernflower and then click Upload and Decompiler and now it is done. loading and you press save and you have fun with it.
