7-Zip 15.02 Alpha with size 4.45 Mb is an excellent archival quality and high, which is beyond many of its competitors and, therefore, more and more users stop option on it. Caring for the developer program is manifested in the deployment of 7-Zip around the world, translating programs in 79 languages in the world, some of whom are Russian.
7-Zip compresses files algorithm LZMA, which is far more advanced algorithm archiver WinRar. Algorithm LZMA data compression technology supports multi and hyper-threading, which also gives the program plus the on platforms with powerful processors, compared with competitors.
7-Zip archives that you can create a password-protected (to decrypt passwords of 17 characters need to be 40-100 years), encrypt file names and of course create self-extracting SFX-archives. Data is encrypted using 256-bit AES encryption algorithm, which is one of the best encryption algorithm today.
In the first place, these records are valuable to its own 7z format. It is believed that this format has the highest compression ratio, and is best suited for archiving large amounts of data (for example, a very large program or game). Formats supported: ZIP, CAB, RAR, ARJ, GZIP, LZH, CHM, BZIP2, TAR, CPIO, RPM and DEB. Need to pay attention to the situation often is the degree of compression ZIP and GZIP formats in this program is much higher than the competition.
7-Zip is free, as well as rare among programs of this kind, then this fact is another good argument to support it.
