- Compression and packaging of files
When you want to email several files, it is better to put them into a package (often called a zip file in Windows). To do this, you can download the free compression software '7zip', which is available either at www.7-zip.org or at CNET. After you have installed '7zip', you can left-mouse-click to select the files that you want to compress and then right-mouse-click to select '7zip'.
