Use it carefully! Please create backup copy before use it.
Please verify content of each archive.
Run only 1 active instance of the program!

How does it work?
Ultra7z FreeArc Optimizer repacks your archives using all possible compression algorithms, trying (sorting) different algorithms for each file type (there is a selection by file extension). At the end, it creates the smallest possible archive size (i.e. it optimizes the original archive, the content does not change!). This is why it is quite a long process (several times longer than simply creating an archive), but it will not affect the speed of unpacking the archive, it will still be very fast (unlike other superarchivers like PAQ, where you have to wait for hours to unpack, here it takes only a few seconds or even less). The compression gain can be up to 10-20% for certain types of files! If the optimized archive is the same size as the original one or larger, the program will leave the original archive unchanged, i.e. you will not lose anything in size in any case.

Thus, the program can also be used as a regular Converter from various types of archives (7z, zip, rar, etc.) to ARC archives.

For daily use, I recommend the “Good” mode, it is fast enough and gives good results. For better compression, use the “Best” or “Ultra” modes. The “Extreme” and “Extreme2” modes can be selected if the archive size is small enough (up to 10-50 MB), or if you want to get maximum compression despite a fairly long repacking process. If you have more than 4 GB of RAM, you can increase the size of the LZMA dictionary to 256 MB and PPMD to 1024 MB, which can further improve compression. Also, a small improvement usually gives an increase of the parameter “LZMA word Size” to 273.

Features:
– Auto switch LZMA/PPMD/GRZIP/EXE/DISPACK/DELTA/DICT/LZP/REP during creation ARC-archives (+ improved (tuned) lzma for jpg, bmp, wav, exe…)
