Notes about the HXS 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 HXS file type is primarily associated with 'Help 2' by Microsoft Corporation.
This file type is a replacement for .CHM.
The H2Viewer program can open HSX files but it requires Microsoft Help 2.0 Runtime Libraries, which may not be installed by default on every computer.
