FlexCompress

FlexCompress is a high-speed compression library developed to provide archive functionality for your applications. This solution provides flexible compression and strong encryption algorithms that allows you to integrate archiving or backup features into your programs in a fast and easy way.

FlexCompress includes our new unique technology, a transaction system. This innovative solution gives you a rapid and simple way of updating archive files providing data integrity like a reliable database system. See also speed and ratio tests.

.NET version of FlexCompress is also available: FlexCompress.NET

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

• Special tuning for compression algorithms implementations
• One of the fastest Deflate implementations available today
• Transaction system optimizing a group of archive modifications

• 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
• Unicode filenames support

• 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.

• Comprehensive help
• Lots of demos
• Easy-to-use interface provided by a single component
