Free Unzip Software Download


My flavor unzip software 7-Zip.It is an open source software. The majority of the source code is under the GNU LGPL license. Therefore, you can use it at home, commercial organization without any registration or payment. 7-Zip works in Windows 98/ME/NT/2000/XP/Vista.

There is a port of the command line version to Linux/Unix. Occasionally, I do have some difficulty to unzip certain documents with Chinese character by using winrar. After using 7-zip, I don’t see any problem yet to unzip any document.

The main features of 7-Zip
• High compression ratio in new 7z format with LZMA compression
• Supported formats:
o Packing / unpacking: 7z, ZIP, GZIP, BZIP2 and TAR
o Unpacking only: ARJ, CAB, CHM, CPIO, DEB, DMG, HFS, ISO, LZH, LZMA, MSI, NSIS, RAR, RPM, UDF, WIM, XAR and Z.
• For ZIP and GZIP formats, 7-Zip provides a compression ratio that is 2-10 % better than the ratio provided by PKZip and WinZip
• Strong AES-256 encryption in 7z and ZIP formats
• Self-extracting capability for 7z format
• Integration with Windows Shell
