The WinZip Computing organization recently released the latest iteration of their utility program, and it has some noteworthy additions. This version is aimed specifically at establishing complete Windows 7 compliance, and it also adds previews for certain file types. Additionally, the automatic wiping feature assures that the temporary file created by WinZip will be "shredded" after the unzipping process is completed. This version is free to try for 45 days, and it is compatible with computers running Windows 2000, XP, Vista and 7.
