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
Speed
- Special tuning for compression algorithms implementations
- One of the fastest Deflate implementations available today
- Transaction system optimizing a group of archive modifications
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
- Unicode filenames support
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.
Ease of use
- Comprehensive help
- Lots of demos
- Easy-to-use interface provided by a single component
- Source code available

I don't think I've ever had a better support experience in regard to any of the 3rd party tools we use.
