To enable Windows functionality, you will have to install the Compressed Folders component. Go to the Control Panel and double-click Add/Remove Programs. Next, go to the Windows Setup tab and from the "Components" window select System Tools and click the Details button. From the ensuing screen place a check next to "Compressed Folders" and then click OK, Apply and OK one final time. At this point you may be asked for your Windows CD, so make sure you have this handy. After the necessary files are installed onto your system, you will need to restart your computer.
If you press the right mouse button you'll see you can now create a compressed folder from the "New" menu. This is how you create an archive and you can add files to it simply by dragging and dropping. You will have to extract files from the archive before you attempt to edit or work with them, of course, and you will have to place them back in the compressed folder manually after you have finished. Instead of copying a file into a compressed archive you can move it (which is the only way you will save space) by right-clicking on the file and dragging it to the compressed folder. Let go of the button and select Move here rather than Copy Here.
If you find dragging and dropping inconvenient, you can extract files from compressed folders by going to the "File" menu or by right-clicking anywhere within the compressed folder and selecting Extract all. From the following screen you will then be able to select the destination folder for the unzipping process.
PASSWORD PROTECTION Compressed Folders can also be used as a form of security, as they can be password-protected to prevent unauthorised viewing of files. To password-protect an archive, right-click it and select Encrypt. Type in and confirm your password, and you're set. Other users will now be able to view what's inside the archive, but they will not be able to extract any files unless they provide the password. Again, this will only be of value if you move your files to the archive instead of copying them.
