Between size optimized SOLID archives like .7z w/ LZMA and non-SOLID archives like .zip w/ Deflate, the Nexus (.nx) format bridges the gap; providing a tradeoff with most of the benefit of both worlds.

We aim to create a simple format, appropriate for both local storage of mods and for downloading from the web.
By using modern compression techniques, we provide both competitive file size and compression speeds.
