Notes about the XTM 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 XTM file type is primarily associated with 'CmapTools' by IHMC. IHMC = Institute for the Interdisciplinary Study of Human & Machine Cognition. Concept maps represent organized knowledge, graphically and textually captured and displayed in CmapTools.
