Visual Zip Studio is tightly integrated with Windows. You can zip and unzip files without needing to open the Studio! This is accomplished by means of shell extensions.
A shell extension is an addition to your operating system that allows it to perform tasks it could not do before. Visual Zip Studio comes with some shell extensions which this book describes. These shell extensions can by themselves do almost everything Visual Zip Studio can.
To access the shell extensions, run Windows Explorer (the shell) and right click on either a zip file, or a group of files. This will bring a list of available shell extensions to view. You can also drag and drop files into an existing zip file, or select the "New" submenu after right clicking on empty space.
