Available as a free to use software application, #7Z is a backup utility that is intended to help users simplify the process of data backup and compression. Supported in Windows 7, XP, and Vista versions, this tool has been designed and developed by Chris Giles. The tool offers 7-Zip GUI for Windows systems and P7Zip GUI for Linux systems. The tool offers an archiving feature that claims to offer one of the highest compression ratios. P7Zip acts as a port for 7-Zip from Windows to Linux. The tool offers the options to update your current archives, backup multiple files to a location, and extract the archived files by making use of the archiving lists and profiles.
