File Viewer Plus supports over 30 archive formats, including popular formats such as Zip, RAR, and 7-Zip (.7Z). After you have opened an archive, File Viewer Plus gives you a preview of the files contained in the file.
Simply click the Extract Archive button to unpack the archive's contents. If the "Extract to same folder" check box is checked, File Viewer Plus will create a folder with the same name of the archive in the same location, and it will place the extracted contents in the folder. If it is unchecked, a save dialog pops up and allows you to select the target extraction location.
