ZoneAlarm Mailsafe renamed MDA file
File type: Various data file
Files with zm1 extension are used by the ZoneAlarm firewall software. They contain some various data for internal purposes.
Found 2 different file type records with the same zm1 filename suffix.
File type category:
Various data file
Date updated: October 16, 2017
The zm1 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 zm1 file extension originally had ZIP file extension (common ZIP compressed archive). Simple renaming will restore the Windows associations with such file, however it is not advised, unless you are absolutely sure it safe to do.
You can rename the zm1 file extension back to MDA 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.

The zm1 file extension is associated with the ZSNES emulator of the Super Nintendo Entertainment System video gaming console that was popular in 1990's.

Use ZSNES to playback *.zm1 movie files.
