ZipMix.exe WIN32 command line 8,704 bytes (02/21/2007)
Sometimes, when you run 2 different .ZIP programs on the same data
(PKZIP & KZIP for example), some files get compressed better in one
program, while other files get compressed better in the other. ZIPMIX
will take the best files from each one and create a new output file,
which is guaranteed to be equal to or smaller in size to both of the
input files. ZIPMIX can also be used to perform boolean operations on
ZIP files, such as merging 2 ZIP files together, or updating a new file
(with some tricks).
ZipMix.c The source code 4,759 bytes (02/21/2007)
RekZip.bat WIN32 command line 379 bytes (07/06/2006)
Here's a little batch file I wrote for KZIP to directly re-compress an
existing ZIP file. I have tried to make the batch file as safe as
possible - meaning you shouldn't lose the original file if there's an
error during one of the steps. I think the worst that can happen is you
end up with a harmless temporary sub-directory - and that's only if
your computer freezes! If you really want to feel cool, you can
re-compress a whole directory of ZIP files using this command: "for %i
in (*.zip) do rekzip %i" : ) Someday, I might actually get around to
integrating this functionality into KZIP.EXE.. |

PNGOUT optimizes the size of .PNG files losslessly. It uses the same
deflate compressor I wrote for KZIP.EXE (see below). With the right
options, it can often beat other programs by 5-10%. That includes
pngcrush -brute, optipng -o7, advpng -z4, etc.. PNGOUT is a great tool
for optimizing the size of web pages or squeezing game content onto
mobile devices. Almost all .PNG files on my website were optimized with
PNGOUT. For a detailed description of the options, please check out thePNGOUT tutorial written by Kerry Watson. Click here for license.
虽然本版本在J2ME领域作为Png压缩工具..但是还有其他许多的功能..自己研究一下吧 |

My own PKZIP-compatible compressor focusing on space over speed. KZIP
creates smaller .ZIP files than PKZIP with maximum compression enabled
and even beats 7-Zip most of the time. I use a few tricks beyond what
your typical compressor will do. The main one is an exhaustive search
of all patterns. The other one is my advanced block splitter. ZIP files
created with KZIP are compatible with all of the latest .ZIP software -
just that if you use KZIP, your file will probably be smaller.
Decompression is still very fast, making KZIP the perfect tool for
shaving off seconds from download times. What will you do for a byte?

A pure java implementation of the java.util.zip library
This project provides an implementation of the java.util.zip classes.
The code is pure java (no native code is used), and we aim to be compatible with existing java.util.zip implementations. Some code was borrowed from libgcj, almost all the rest was written by Jochen Hoenicke. |
