Notes about the SZP file extension:
To open this file type, a required software must be installed. Without it you only see a Windows message "The following file cannot be opened
" (Windows 7) or "How do you want to open this file?
" (Windows 10) if you double-click the file. There click on "More apps"
and choose a suitable software to view such files on your PC or from email attachments.
The SZP file type is primarily associated with 'SecureZIP PartnerLink' by PKWARE, Inc..

Sponsor organizations can extend their security policies and best practices to an unlimited number of partners by offering them SecureZIP Partner, a free version of SecureZIP.
The Policy Manager saves policy settings and information about contingency keys to a policy file with a .szp extension.
