A compressed folder has the standard, yellow folder icon but the front has a zipper running up and down through the middle of the folder. You will have to decompress the files in the zip folder before the files can be used. To decompress a zipped folder:
1) Single right click on the zipped folder icon. A sub menu window is displayed.
2) Select "
Extract All..." on the sub menu. A window opens stating you need to "
Select a Destination and Extract Files"
3) Select the "
Extract" button at the bottom of the window.
4) A folder will be created in the same location as the original, zipped folder. The new folder icon will look like a normal folder and will not have the zipper on the icon. The new folder will share the name of the zipped folder and will contain decompressed files.
