The file module is able to create, write and read cross-platform EDGELIB package files. These package files contain a list of resource files that can be compressed using various methods. This is useful for reducing and grouping game data.
Files can be compressed using Zlib (G-Zip) or an internal Edge compression algorithm. Additionally, compression can be disabled.
The EDGELIB Packer tool is included in the EDGELIB SDK and offers advanced GUI and commandline interfaces to manipulate EDGELIB packages.
The file tutorial contains a page about EDGELIB package files.
