Help and documentations are in English. 7-Zip is a free and open-source file archiver, a utility used to place groups of files within compressed containers known as “archives”. It is developed by Igor Pavlov and was first released in 1999. By default, 7-Zip creates 7z-format archives with a . Each archive can contain multiple directories and files. As a container format, security or size reduction are achieved using a stacked combination of filters. These can consist of pre-processors, compression algorithms, and encryption filters.
The native 7z file format is open and modular. File names are stored as Unicode. The 7z file format specification is distributed with the program’s source code, in the “doc” subdirectory. 7-Zip can open some MSI files, allowing access to the meta-files within along with the main contents.

When compressing ZIP or gzip files, 7-Zip uses its own DEFLATE encoder, which may achieve higher compression, but at lower speed, than the more common zlib DEFLATE implementation. The 7-Zip deflate encoder implementation is available separately as part of the AdvanceCOMP suite of tools. The decompression engine for RAR archives was developed using freely available source code of the unRAR program, which has a licensing restriction against creation of a RAR compressor. 06 and later support extraction of files in the RAR5 format.
7-Zip comes with a file manager along with the standard archiver tools. The file manager has a toolbar with options to create an archive, extract an archive, test an archive to detect errors, copy, move, and delete files, and open a file properties menu exclusive to 7-Zip. The file manager, by default, displays hidden files because it does not follow Windows Explorer’s policies. When going up one directory on the root, all drives, removable or internal appear. Same as “Computer” except loads the drives in low-level NTFS access. This results in critical drive files and deleted files still existing on the drive to appear. NOTE: Access to the active partition in low-level mode is not allowed for currently unknown reasons.
