JurikSoft Compression Library is a .NET component with a set of methods, which allow
Compress array of bytes using lossless compression algorithms.
Current version of compression library include following compression algorithms: LZSS,
Adaptive and Non-Adaptive Prefix Codes and Run Length Encoding algorithm.

High efficient Data Compression Library for use with Delphi, C++ or VB. Support Rank, ZIP, BZIP and PPM compression algorithms. Compression ratio more than 1.5-2 times better than ZIP/RAR archiver. Compression speed up to 8 Mb/sec (on PIII-600).

With Easy Compression Library you can add advanced compression and encryption functionality to your projects.
Key Features: Advanced compression algorithms, Compression on-the-fly, No DLLs, compiles right into your EXE, Strong encryption

HTMLCompact is a powerful HTML compression tool created for webmasters. Its effective compression algorithm can reduce the size of your pages by as much as 80% while keeping the appearance of the page the same. By using HTMLCompact, your web pages will become much smaller which results in faster load times, saving you both bandwidth and disk space.

NTFS offers file based compression but the compression rate isn't displayed anywhere. For any folder on an NTFS volume, NTFSRatio shows the size and the compression rate of this folder and also of its subfolders. Compression and decompression can be done inside NTFSRatio with immediate review of the result. Results can be printed or exported. NTFSRatio can be called from the Explorer context menu of any folder.

The addZIP Compression Components are the simplest way to add the industry-standard PKZIP compatible file compression and decompression to your programs. These royalty-free, multithreaded ActiveX/COM components are compatible with all 32-bit development software including Visual Basic 6/.NET, C/C++, Delphi and Visual FoxPro. The addZIP and addUNZIP components have no user-interface so they can be used both in desktop and server applications.

Fast compression, compatible with the ZIP industry standard, and command line support. 12-Zip has Explorer integration, a graphical window to manage zip files, for example add, freshen, move, or update files, supporting different compression methods, and features a small executable. Now supports Zip2, up to 20% smaller zips!

Xceed Streaming Compression for .NET is an efficient and lightweight data compression class library for .NET and ASP.NET. It can process any size byte array with ease and provides a true .NET pass-through stream for compressing or decompressing any .NET stream's data on the fly. It supports the GZip, Zlib, Deflate and Deflate64? formats and is available with its 100 % managed C# source code.

High-performance and easy-to-use compression/encryption library. It has the all you need to compress and encrypt files, memory buffers and strings.
-Wide range of compression algorithms and modes
-Extremely fast modes
-Better rate than Rar, Zip, BZip
-Strong encryption - AES Rijndael
-One stream for transparent compression/decompression for write/read
-Forward and backward seeks in stream
-Read and write any portion of data

New compression format. Infima Compression Library SDK was built from the ground up for better compression ratio and speed but not at the cost of performance. The LAN format is a new archive format, providing high compression ratios and speed for most data types, it provides a platform for managing and creating data archives which are 10%-85% better than other products.

ActiveX OCX to compress files in the Bzip2 format , ability to pause , resume and cancel the compression execution , the compression code is loaded dinamically in the process of the software using the control ,the control can provide progress information about the compression and decompression functions , the code execution is optimized for speed

CompressionMaster Suite is the most advanced data compression library available for Delphi and C++ Builder. The Suite includes three independent data compression products: Easy Compression Library, FlexCompress and ZipForge.

This is a unique tool that allows you to store your images with a higher compression ration and unavailable to the others to be seen. Each personal copy of the tool provides unique encryption algorithms that make different private copies incompatible of reading images compressed and encrypted by other personal releases.

Reduce unnecessary diskspace for image files on your hard disk using Image Compressor. Although images can be stored in various formats on your PC, the Jpeg file format is a form of image storage/compression which reduces the disk space for each image file whilst remaining almost undetectable to the human eye. Compression ratios up to 1:20 can easily be achieved without much loss of quality. This can therefore save a lot of unnecessary disk space

SharpZipLib is a free, open-source compression library for .NET. It supports Zip, Gzip, Tar, and Bzip2, and also computes checksums. The library currently lacks Zip file splitting/spanning, customizable self-extracting Zip files, and reading and writing directly to memory. It is ported from the GNU Classpath Zip library for Java. The library and source code is distributed under the GNU General Public License, with an exception.
