Notes about the SZR 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 SZR file type is primarily associated with 'SpeedZapper' by SpeedZapper. Browser add-on that lets you store your bookmarks from your browser into searchable database classified into topics. The .SZR file can be shared with others who have the software.
