Additional information:

* 7-Zip compresses files using the LZMA algorithm, which is much more advanced than the WinRAR archiver algorithm. The LZMA data compression algorithm supports multi- and hyper-threading technologies, which also gives the program a plus on platforms with powerful processors in comparison with competitors.
* In 7-Zip, it is possible to create archives that are password protected (it will take from 40 to 100 years to decrypt a password of 17 characters), encrypt file names and, of course, create self-extracting SFX archives. The encryption uses 256-bit cryptographic algorithm AES, which is one of the best encryption algorithms currently.
• First of all, this archiver is valuable with its own 7z format. It is believed that this format has the highest compression ratio and is excellent for archiving large amounts of information (for example, especially large programs or games). The following formats are also supported: ZIP, CAB, RAR, ARJ, GZIP, LZH, CHM, BZIP2, TAR, CPIO, RPM and DEB. It is worth paying attention to the frequent situations in which the compression ratio of ZIP and GZIP formats in this program is an order of magnitude higher than that of competitors.
* 7-Zip is completely free, and since this is an infrequent phenomenon among programs of this kind, this fact is another good argument in its favor.

Some features:

* Archiving/unzipping: 7z, XZ, BZIP2, GZIP, TAR, ZIP and WIM
* Unzipping only: ARJ, CAB, CHM, CPIO, CramFS, DEB, DMG, FAT, HFS, ISO, LZH, LZMA, MBR, MSI, NSIS, NTFS, RAR, RPM, SquashFS, UDF, VHD, WIM, XAR and Z.
• For ZIP and GZIP formats, the 7-Zip archiver offers compression that is 2-10% better than the compression provided by PKZip and WinZip archivers
* Strong encryption in 7z and ZIP formats
* Self-extracting capability for 7z format
* Integration into Windows Explorer
* Powerful file manager
* Powerful command line version
* Plugin for FAR Manager

Changes:

19.00 Final (2019-02-21)
The encryption strength for 7z archives has been increased:
the size of the random initialization vector has been increased from 64-bit to 128-bit,
and the pseudorandom number generator has been improved.
- Some bugs have been fixed.
