What is an .ZL1 file?
.ZL1 file extension is created by Check Point Software Technologies Ltd.. .ZL1 has been classified as Various data Files.
.ZL1 is ZoneAlarm Mailsafe renamed ADP file
The ZL1 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 ZL1 file extension originally had ADP file extension (most likely Microsoft Access project 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.
