recomendations of compression programs to be added both in the article itself and the in comparison table.


1. NanoZip @NanoZip.net

NanoZip is an upcoming file archiver. It consists of several original compressors, put into a single file archiver program. The project goal is the highest possible compression efficiency.


2. FreeArc @FreeArc.org

FreeArc is a modern general-purpose archiver. FreeArc is fast but efficient compression and rich set of features.

Advantages:

- Free, open-source, with console and GUI versions for both Windows and Linux. - Includes LZMA, PPMD, TrueAudio and generic Multimedia compression algorithms with automatic switching by file type. - Filters that further improve compression: REP (finds repetitions at the distances up to 1gb), DICT (dictionary replacements for texts), DELTA (improves compression of tables in binary data), BCJ (executables preproccesor) and LZP (removes repetitions in texts). - Special compression algorithms are used in fast compression modes (GRZIP for texts and Tornado for binary data). - Overall, 11 compression algorithms and filters are included (compared to 3 in 7-zip and 7 in RAR) and this number still grows. - Smart file sorting that groups similar files together and fully customizable sorting order. - Typically, FreeArc works 1.5-3 times faster than best programs in each compression class (ccm, 7-zip, rar, uharc -mz, pkzip) while retaining the same compression ratio; from technical grounds, it’s superior to any existing practical compressor.

Disadvantages:

Compared to RAR and 7-zip, FreeArc at this moment lacks the following: multi-volume archives, 64-bit version, storing of file attributes/extended timestamps/NTFS streams in the archive, bcj2, data segmentation. These are planned to be fixed in subsequent versions.
