Notes about the XR file extension:
Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries
, unused processes and other unfavourable system settings to identify slowdown issues.
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.
