Notes about the XRX 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 XRX file type is primarily associated with 'Expression Encoder' by Microsoft Corporation. Microsoft Expression Encoder, a feature of Expression Media, offers encoding, enhancement, and publishing of rich media experiences to Microsoft Silverlight. This file is used for saving media profile settings. Expression Encoder also opens Windows Media Encoder .PRX files. However, once settings derived from a .PRX are customized by the user, the result may only be saved for later use as an .XRX file.
