Dynamite is a tool and library for decompressing data compressed with PKWARE Data Compression Library and it was created from the specification provided by a post in the comp.compression newsgroup.
http://synce.sourceforge.net/synce/dynamite.phpStuns
This program tries to unpack the given file by application of several algorithms byte-by-byte. Result of work of the program is the set of files with the unpacked data. Many of the produced files are not correct. However, among them there can be correctly unpacked data. Correctly unpacked files have […]

Mp3stat is Linux a utility program to compare encoders against an MP3 that was VBR encoded. It outputs a linear graphical bitstream analysis of each MP3 being compared and gives you a breakdown of how many frames of each bitrate are found in the MP3. It basically allows you to see how encoders treat areas […]

DynaZIP offers just about everything you’d want to work with Zip files in a Win32 environment.
DataCompression.info user Mike L. had this to say: Creates huge output executables. Features contained in multiple packages are contained in a single package in comparable products. Pricing is very steep compared to comparable products.
PowerArchiver
Yet another Windows archiving program. PowerArchiver comes with a nice long list of supported formats: ZIP, CAB, LHA (LZH), TAR, TAR.GZ, TAR.BZ2, BH, RAR, ARJ, ARC, ACE, ZOO, GZ, BZIP2, XXE, and UUE. Plus a built-in viewer for JPG, GIF, and a few other formats.
Release 9.0 of PowerArchiver shipped July, 2004.

Taking Advantage of libpng
Reputedly an excellent set of resources for using libpng - but don’t take my word for it - my Japanese is non-existent.
http://www5.cds.ne.jp/~kato/png/FreeImage
FreeImage is yet another free library for image reading, writing, and manipulation. FreeImage supports a long list of compressed formats, including JPEG, PNG, TIFF, and more. Claims to support multiple platforms, but it does apear that most of the experience with this project is on Win32 systems.
Version 3.4.0 is shipping in July, 2004.

I’m pleased to announce with my co-authors availability of a preprint on our new algorithm to estimate the Shannon entropy rate (bits/symbol) or (bits/sec) of an observed sequence of low-alphabet symbols. It uses the Context-Tree-Weighting universal compression method, but doesnot use the compression ratio directly as an entropy estimator but as a scaffold for a […]
