Notes about the RA3 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 RA3 file type is primarily associated with 'RA3DIO' by xeraina GmbH. RA3DIO is a virtual reality tool that supports the design, optimization and management of radio network systems.
