This is an advanced packer which packs files into either the Zip, JAR or GZIP package formats. This is a bit self explanatory so no need for an explanation.

Well done Big Grin and btw, might I ask... how are YOU able to Javax.Swing??? :O I have been searching all since last night, and I can't find out how anywhere... how am I supposed to script UI when I can't even set the window size? D: Hell, I can't even manifest a window! Again, excellent program Big Grin

I highly recommend using an IDE for such, for example, NetBeans has a great GUI edittor. As for knowing how to use Swing, I highly suggest either looking at the Java tutorials for that topic, or find a good ebook or reference off the internet on how to do some basic Swing apps.

If you need help, dont hesitate to ask.

Aww but I have begun doing just that! I downloaded Netbeans thinking it contained the classes and methods for the Javax.Swing, but actually it was a compiler! In fact, it was designed to design UI, lol.

It does but you need to navigate with NetBeans for a bit. Maybe I will create a tutorial for you on how to get started with Swing soon.
