Notes about the RW3 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 RW3 file type is primarily associated with 'RapidWeaver' by Realmac Software Limited. RapidWeaver is Web design software made exclusively for the Mac.
