FreeArc

FreeArc is a free and open-source file archiver and compressor. It was developed by Ivan Pavlov and is known for its high compression ratios and speed. FreeArc supports a wide range of compression algorithms, including LZMA, PPM, and BWT, and offers various features such as solid archiving, data deduplication, and self-extracting archives. The software is available for Windows and Linux operating systems.

One of FreeArc's key strengths is its ability to achieve very high compression ratios, often outperforming other popular archivers like RAR and 7z on certain types of data. This is attributed to its advanced algorithms and flexible configuration options. Users can fine-tune compression levels, dictionary sizes, and other parameters to optimize performance for specific needs.

FreeArc also includes features for managing archives, such as split archives, recovery records, and password protection. Its command-line interface makes it suitable for scripting and automated tasks, while a graphical user interface is also available for easier use. The project is actively maintained, with regular updates and community support. FreeArc is distributed under the GNU General Public License.
