Small code size for decompression: about 5 KB.

If you decide to always open 7Z files with the program, only check the option 'Always use the selected program to open this kind of file'. In the pop-up windows, choose a program as the 7Z file opener. Right-click on the 7Z file and go through 'Open with' > 'Choose default program'.

Small memory requirement for decompression (depend from dictionary size) a) Select a program to open 7Z files on Windows.Decompression speed: about 10-20 MB/s on 2 GHz CPU.Compression speed: about 1 MB/s on 2 GHz CPU.LZMA is the default and general compression method of 7z file format. Support for very large files with sizes up to 16000000000 GBħz file format has an open architecture, so it can support any new compression methods.Ability of using any compression, conversion or encryption method.

MIME type used for 7z files: application/x-lzma The main features of 7z file format: To increase the cost of an exhaustive search to crack a password, 7-Zip uses a large number of iterations when it produces a cipher key from a password.ħz file format was developed as as part of the 7-Zip compression utility distributed under the GNU LGPL. A key derivation function produces a derived key from the text password entered by the user. To create that key, 7-Zip runs a derivation function based on a SHA-256 hash algorithm. This algorithm uses a cipher key with a length of 256 bits. The 7z file extension is used for native file format of 7-ZIP archiver.ħz is the new backup and archive file format, providing high compression ratio.ħ-Zip supports encryption with the AES-256 algorithm.
