FlexCompress 2.73 – High Compress Library

Posted in Development Software, Software Companies, Utilities, Windows


A compression tool that gives better compression than Winzip and WinRar, incredible isn’t it? Well, that will be FlexCompress 2.73. This software is a high-spede high-speed compression library developed to provide archive functionality for your applications, and some of the functions include flexible compression and strong encryption algorithms, which allow users to integrate archiving and backup features in your program easily and quickly.

Incorporating their new unique technology, a transaction system, FlexCompression is an innovative solution that gives quick and easy fix to update archive files, providing data integrity, just like a reliable database system.


  1. Target Development Environment:
    Delphi 4, Delphi 5, Delphi 6, Delphi 7, Delphi 2005, Delphi 2006 and C++ Builder 4, C++ Builder 5, C++ Builder 6, C++ Builder 2006. Trial edition of Delphi is not supported.
  2. Target OS:
    Windows 95/98/ME, Windows NT, 2000, XP


  1. Compression and encryption algorithms
    • * Wide range of compression algorithms: ZLib, BZip and PPM with different compression levels
    • * Creates encrypted archives using strong encryption algorithms: Rijndael 128 and 256 bit version, Advanced Encryption Standard (AES) winner, DES Single and Tripple, Blowfish 256 bit, Twofish 128 and 256 bit, Square 128 bit, hash RipeMD-128 and RipeMD-256
    • * Fastest compression levels are extremely fast
    • * Good balanced compression levels provide both good compression rate and high speed
    • * Maximum compression levels provide much better compression rate than Zip, RAR and BZIP
  2. Speed
    • * Special tuning for compression algorithms implementations
    • * One of the fastest Deflate implementations available today
    • * Transaction system optimizing a group of archive modifications
  3. Functionality
    • * Adds, moves, extracts, deletes, updates, tests, refreshes a group of files by a single operation
    • * Supports in-memory archives
    • * Stores archives in TStream descendant objects like BLOB streams
    • * Compresses large files with low memory consumption
    • * Provides compression for files, buffers, streams and strings
    • * Repairs and opens corrupted archives
    • * Supports archives up to 2^63 bytes, compresses and decompresses files up to 2^63 bytes
    • * Creates multi-disk spanning archive
    • * Splits archive to multiple volumes
  4. Convenience
    • * Native VCL; no DLLs; no OCXs
    • * Well-designed component interface
    • * Progress indication with possibility to cancel operation
    • * Lots of useful events such as OnOverwritePrompt, OnNeedPassword, OnProcessFileFailure, etc.
  5. Ease of use
    • * Comprehensive help
    • * Lots of demos
    • * Easy-to-use interface provided by a single component
    • * Source code available

Two editions are available, the trial version and the commercial version. The former can be downloaded for free, whereas the latter costs €79 for a single developer use (no source code).
