CAM UnZip is a free compressor and file extractor that works with ZIP files. To unzip all the contents of the zipped folder, press and hold (or right-click) the folder, select Extract All, and then follow the instructions. To unzip a single file or folder, open the zipped folder, then drag the file or folder from the zipped folder to a new location. Although highly compatible both with PKWARE's PKZIP and PKUNZIP utilities for MS-DOS and with Info-ZIP's own Zip program, our primary objectives have been portability and non-MSDOS functionality.
