Excel spreadsheets can contain massive amounts of data. You may find that an Excel spreadsheet you've created is simply too large to store on your flash drive or to send in an e-mail. The solution to this problem is to compress the Excel spreadsheet by placing the file in a compressed, or zipped, folder. Compressing your spreadsheet allows you to reduce the size of the file without losing your data.
Hover your pointer over the Excel spreadsheet file and right-click it. A menu will appear.
Locate the command on the menu that deals with zipped or compressed folders. This command will be something like "Add to Zip file," "Send to Compressed (zipped) Folder" or "Create a Compressed Folder."
Click on "New" or "Create New" if you can't find a command that directly deals with zipped or compressed folders. From the new menu that appears, you should be able to find the proper command.
Click on the command once you locate it. This will compress the Excel spreadsheet into a compressed or zipped folder.
Right-click a blank space on your desktop if you can't locate a proper command from the Excel menu. Select "New," and click "Compressed (zipped) Folder." This will create a compressed folder on your desktop.
Click on your Excel spreadsheet file, and drag it into the new compressed folder.
