Notes about the IQR 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 IQR file type is primarily associated with 'CADIQ' by ITI TranscenData. CADIQ analyzes, identifies, and highlights potential shape and fit (geometry and topology) problems within CAD models that may affect downstream applications. The IQR file contains an archive of CADIQ analysis results.
