7-Zip File Manager 32 and 64-bit Free Download

7-Zip is an open source file archiver. 7-Zip operates with the 7z archive format, but can read and write several other archive formats. The program can be used from a command line interface, graphical user interface, or with a window-based shell integration. 7-Zip began in 1999and is actively developed by Igor Pavlov. The cross-platform version of the command line utility, p7zip, is also available.

7-Zip is open source software. Most of the source code is under the GNU LGPL license. The unRAR code is under a mixed license: GNU LGPL + unRAR restrictions. 7-Zip won several awards, including the SourceForge.net 2007 community choice awards for "Technical Design" and for "Best Project".

Features:

7-Zip supports:

• The 256-bit AES cipher. Encryption can be enabled for both files and the 7z directory structure. When the directory structure is encrypted, users are required to supply a password to see the filenames contained within the archive. WinZip-developed zip file AES encryption standard is also available in 7-Zip to encrypt ZIP archives with AES 256-bit, but it does not offer filename encryption as in 7z archives.
• Volumes of dynamically variable sizes, allowing use for backups on removable media such as writable CDs and DVDs.
• Usability as a basic orthodox file manager when used in 2-panel mode.
• Multiple-core CPU threading settings can be configured.
• The ability to attempt to open EXE files as archives, allowing the decompression of data from inside many "Setup" or "Installer" or "Extract" type programs without having to launch them.
• The ability to unpack archives with corrupted filenames, renaming the files as required.
• The ability to create self-extracting single- (but not multi-) volume archives.
• Command-line interface.
