plzip is a parallel implementation of the lzip lossless data compressor. It uses the lzlib library and processes separate chunks of input concurrently, allowing modern multicore processors to accelerate compression and decompression.
The program produces files compatible with the lzip format. Its parallel approach is particularly effective with large inputs, where independent compression members provide sufficient work for multiple threads.
Like lzip, plzip places importance on data integrity and dependable long-term storage. Its multimember output provides a degree of resilience against corruption because undamaged members can potentially be recovered independently.
This is free and open source software.
Key Features
- Parallel lossless compression using the lzip file format.
- Uses multiple worker threads for processing independent input chunks.
- Supports parallel decompression of multimember lzip files.
- Produces compressed data compatible with standard lzip implementations.
- Automatically selects suitable dictionary sizes without exceeding configured limits.
- Allows dictionary sizes, compression levels and processing threads to be adjusted.
- Includes an integrity test mode for compressed files.
- Lists compressed sizes, original sizes and compression statistics.
- Can display the positions and sizes of individual compressed members.
- Supports recovery workflows using lziprecover.
- Preserves timestamps, permissions and file ownership where supported.
- Processes standard input and output, including suitable named pipes.
- Can retain original files during compression and decompression.
- Provides a recompression option for files already using a compressed suffix.
- Cross-platform support – runs on Linux and Windows.
