Notes about the XMO 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 XMO file type is primarily associated with 'Authorware' by Adobe Systems Incorporated. Authorware was a Macromedia product. Macromedia was taken over by Adobe. Movie drivers are necessary when showing Authorware-produced movies. Generally, the XMO file name will start with A5, A6, A7... indicating the version of Authorware used to produce the movie. The rest of the name will indicate the type of driver: vfw32 = AVI, mpeg32 = MPEG, wmp32 = WMV, qt32 = Quicktime and maybe others.
