What is a .ZM9 file?
The .ZM9 file is a special kind of Zip file. It's been renamed by a security feature called MailSafe, which is part of the ZoneAlarm software. ZoneAlarm is a program that helps protect your computer from harmful things like viruses. MailSafe checks email attachments to make sure they're safe. If you get an email with a .ZM9 file, it means MailSafe has changed its name from .ZIP to .ZM9 to prevent it from possibly harming your computer before it checks the file.
To open a .ZM9 file, you can use ZoneAlarm Pro Firewall or a program called Corel WinZip. However, because a .ZM9 file is really just a Zip file with a different name, you can also make it work with any program that opens Zip files. To do this, you change the file's name from whatever.zm9 to whatever.zip. After you rename it, you can open it like any other Zip file to see what's inside or use it. Remember, it's important to be sure that the file is safe before you open it, especially if it came from an email attachment.
