    Precomp is a command line precompressor. You can use it to achieve better compression on some filetypes (works on files that are compressed with zLib or the Deflate compression method). Precomp tries to decompress the streams in those files, and if they can be decompressed and "re-"compressed so that they are bit-to-bit-identical with the original stream, the decompressed stream can be used instead of the compressed one.

    The result is a .pcf file (PCF = PreCompressedFile) that contains more decompressed data than the original file. Note that this file is larger than the original file, but if you compress it with a compression method stronger than Deflate, the compression is better than before.

    What do you think of this?

    I tried and works great!!! the compression it's okay , need to know the switches, ex: more documentation is good

    I miss:

    - the option to open the code
    - documentation
    - improve speed
    - add more algorithms, i know is using zlib and it's in preparation gzip, but what about LZS, huffmans or similars?


    i tried with a few games prepacked with zlib, played extracting/reconverting data and repack again and works great, not too bad for an alpha stage, sure have a bug
