Thanks Jeff and sure thing!

Actually with this tool, I was planning to build it on a separate exe/process so it will be lighter on the engine source side and somehow easier to manage. I have seen your work btw and it looks great as well and almost complete. I thought T3D already has all of zip I/O functions so what issues are you having? Of course with this tool I will be using an external zip library.
Are the packages set up in a particular way? Since it sounds like it's distinct from just regular old zips.
I think this will depend on the user on how the content of package will be exported, but mostly and in the meantime it will follow current T3D folder structure.
