.ZMC File

The ZMC file extension is associated with ZoneAlarm, a personal firewall software, originally created by Zone Labs and currently developed by CheckPoint Software Technologies LTD.

One of ZoneAlarm features is MailSafe, which detects e-mail attachments and warns the user about their presence. When a potentially dangerous attachment is detected, the program quarantines the file with simple renaming of its original file extension, so it breaks the common program association function in Windows and prevents such files from being executed (or launched via associated program).

A file with ZMC file extension originally had EML file extension (common e-mail message file). Simple renaming will restore the Windows associations with such file, however it is not advised, unless you are absolutely sure it safe to do.

The ZMC file extension is affiliated with ZoneAlarm, this software detects dangerous e-mail attachments and warns the user e.g. MailSafe wich is one of ZoneAlarm features. The program secures the file with renaming of its original file extension.

How to open:

You can rename the ZMC file extension back to EML and work with the file normally. This can however be potentially dangerous, because the file was quarantined for a reason. So always re-check it with your anti-virus or anti-spyware programs before you rename the files.
