Notes about the XR 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 XR file type is primarily associated with 'Chaos Desktop' by Chaos systems AB. Chaos desktop is two products in one; one is a document manager that collects data, works with automatized data routines, creates data from templates, and creates metadata. The second is the user interface for the project server Chaos server.
