    I think new compressor is Leonardo - IMHO, the greatest from four.

    In addition, Leonardo is my favorite turtle!

    By the way, Nania, maybe you can explain some basics about your new program? What you've done, details about new algo, etc.

    thanks to all indeed! Sure I become account that is a strange program! Much fast and enough powerful one in compression! it uses an algorithm similar to the Fpaq0s6 series but with some changes for being the much fastest one!

    One disadvantage is that decompression speed is about the same as compression. At the same time, for example, LZPM has MUCH faster decompression (it's just the goal of this compressor).

    Good! Compression near "rar -m2" and "uharc -mz" but more efficient in my opinion.
