The zip format of a file is an open-source format for access to information. It is defined in a special structure ZIP Application Note. The information that can be recorded in two comparable Zip file headers is equivalent by definition. In other words, the information or data recorded in the central directory should be an exact copy of the data available in the local directory. It needs to be accurate. As the Zip file format is open, there is an equal likelihood of receiving a Zip file with simple header issues. It may be a minor mistake when creating the Zip file in an application or software. However, the WinZip can report to you the minuscule mistakes and will treat any inconsistencies in the file format or header information as a potential security risk and report to you that the file is corrupt. Some of these issues may be solved through the Zip file fix routine.
