JPack is an ActiveX DLL and provides methods for programmatically creating and modifying packages in the 'JPack' file format. The package is uncompressed and very basic.

The whole package is loaded into memory, then the files are cached into a temp directory (specified or automatic).

Bacause of this, once the package has loaded you can have fast, native access to the files. As well as the JPack DLL, I have included a custom packaging application called 'JPackager', this is to assist in design-time editing of packages.
