Many companies block certain file extensions, such as EXE and ZIP, from entering an email server to prevent security issues and protect sensitive information. In some instances, however, a ZIP file containing important information must pass through the filter, and an employee can request that the sender rename the file's extension to PIZ to allow the file to reach its destination address. To open a PIZ file, you must enable the viewing of file extensions on your computer, rename the extension and open the file using a file-management tool.
