7-Zip 26.03 Portable is a very good and high-quality archiver for Windows that outperforms many competitors, making it a popular choice for more and more users. The developer’s dedication to distributing 7-Zip worldwide and translating it into 79 languages, including Russian, is evident.
Advanced Compression Algorithms
7-Zip compresses files using the LZMA and LZMA2 algorithms, which are significantly more advanced than the WinRAR archiver’s algorithm. The LZMA and LZMA2 data compression algorithms support multi- and hyper-threading technologies, which also gives the program an advantage over its competitors on platforms with powerful processors.
Strong Encryption
7-Zip can create password-protected archives (a 17-character password would take 40 to 100 years to crack), encrypt file names, and create self-extracting SFX archives. Encryption uses the 256-bit AES cryptographic algorithm, one of the best encryption algorithms available today.
The 7z Format
First and foremost, this archiver is valuable for its proprietary 7z format. This format is considered to have the highest compression ratio and is ideal for archiving large amounts of information, for example particularly large programs or games. It also supports the following formats: ZIP, CAB, RAR, ARJ, GZIP, LZH, CHM, BZIP2, TAR, CPIO, RPM, and DEB. It is worth noting that this program’s compression ratio for ZIP and GZIP formats is often significantly higher than that of competitors.
Completely Free
7-Zip is completely free, which is a rare feature among programs of this type, making it another strong point in its favor.
