open 7Z file

File type: Compressed

 

The 7Z file extension is the default format of the compressed archive developed by Igor Pavlov called 7-Zip. This file compression utility implements the LZMA compression, an open-source algorithm characterized by its higher compression ratio.

It can also produce archives with 256-bit (AES-256) encryption security coupled with a support for Unicode filenames and archive header compression. The maximum file size supported by the 7Z file extension is 16,000,000,000Gb. Aside from the default LZMA compression method, this utility also supports the BCJ2, Deflate, PPMD, and BZip2 compression algorithms.

The 7Z file extension mainly features an open architecture with the capability of using virtually any available method for encryption, conversion, and compression. It is also one of the few compression utilities in the market that present a solid compression ratio. Due to its open-source architecture, it has the functionality of supporting optimized and improved LZ77 algorithm versions. It also supports 32-bit x86 executables for both BCJ and BCJ2.
The 7Z file extension has a variable dictionary size of up to a maximum of 4Gb with a compression speed of 1Mb per second on a 2GHz processor while exhibiting a decompression speed of 10 to 20Mb per second on the same type of processor. It also requires minimal memory requirement for its decompression operation including inherent support for hyper- and multi-threading processor functionalities.
