| BZ2 is a compression engine completely compatible with the original BZ from Mika Heiskanen and its evolution BZ49. BZ2 compress more and faster than its predecessor, while achieving full compatibility. BZ2 typically compresses 40-100% faster than BZ and decompresses ~50% faster, while at the same time seeing the same or better compression. It also uses less memory. Multiple versions are included, including one optimized for speed while achieving the same compression ratio as BZ, and another optimized for compression, while still performing better than BZ. |

Encryption and compression library, originally by Arthur Patrouchev, ported to the 49 series by Yoann Désir.
LZD is a new compression program specifically developed to achieve very high compression and decompression speed. It's typically 3 times faster than BZ and uses less memory, while often providing slightly better compression. Although it is fast, LZD provides very good compression ratio, especially on small and complex objects (e.g. games). For even more speed, a compatible derivative named FastLZD is also provided.
This program reviews the compressed archives of your system. Made in System RPL.
Stacker4x compresses and decompresses on the fly all data handled by the user, so that the user can enjoy the benefits of compression without thinking about it. Everything is fully automated and once the library is installed, it will activate itself and intercept calls to STO and RCL. Compression is provided by FastLZD, and it is very fast (5x-10x faster than BZ), to the point of being hardly noticeable for most objects.

Tool that when being combined with TNT, does compression of several archives, something efficient and fast.
Easy-to-use, but not completely stable, file compressor. This almost always achieves a better compression ratio than BZ, although it takes about 15% longer for compression and decompression. Also decompresses BZ files.
