Notes about the SQJ 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 SQJ file type is primarily associated with 'AXIS Camera Explorer' by Axis Communications. ACE (AXIS Camera Explorer) is an add-on component for Windows that provides access to Axis Network Cameras and the images they produce. Movie files created with ACE are saved with the extension .SQJ. These files are simply a group of image files.
