Zip programs allow users to zip a file. Each zip program uses the same basic functions. This compresses the file so that it is smaller. At times, people need files set at a certain file size. If the file size is greater than the persons need, they can break the zip file into several sections. The first file has an extension of *.zip. The remaining files have a number in the extension to identify what number the file is in the set of split files.
Find the first file in the split files. This is the file with the extension *.zip.
Double-click on the file to open it.
Click the "Extract" button and the program will unzip each file in the series of split files.
