The ZIP file format is the most commonly used compression formats on Windows operating system for file compression. A ZIP file may contain one or more files. By compressing the files, their overall size can be reduced to some extent. These files then can be viewed or accessed by unzipping or uncompressing the .ZIP file. However, a zipped file will not open unless you repair bad zip file, if it is an incomplete ZIP file i.e. it has not downloaded properly or it has not been prepared properly.
