How to Fix a File Headerby Jason Candanedo
When a ZIP file is corrupted or damaged, the objects contained within the file are unfortunately inaccessible. File system or header corruptions cause the ZIP file to become damaged. When a ZIP file is damaged and you try to unzip the file to extract the contents, the process will fail because the file is not whole. You can use free file repair software from the Internet to rectify this problem. After you repair the ZIP file, you can then proceed to extract the contents to your hard drive.
