Dragon unPACKer is a utility designed to open and explore game package files. Unlike other utilities, DUP supports file types of over 80 games. The package files are files where all the resources of a game are bundled. Maps, models, textures and even the code can be all inside a package file. It is common for mod developers to use resources of the original game to help them with their own development. That is why unpackers are popular in the mod community. But no program has as many files supported as this. Also, if the game is not supported, there is still hope, because the program includes a utility called HyperRipper. What this does is searches for patterns in the files so they can be extracted like the others. It is not 100% reliable, but is an option you can have. The interface is very similar to a file explorer, and you can extract any file you want. It also includes a small utility called Duppi, so you can download new pattern plug-ins and support more games. This is a complete unpacker. If you handle files from different games, this is the only program you need.
