Notes about the AUX 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 AUX file type is primarily associated with 'ChiWriter'. ChiWriter is a scientific multifont word processor. It was developed and, until 1995, commercially distributed by Horstmann Software Development Corporation, USA. It was designed to work in an MS-DOS environment, though it can also be launched from an icon under Windows 3.xx or Windows 95. It creates its own graphic screen, and some of the resolutions offer mouse support. However, the lack of true Windows support probably led to the downfall of ChiWriter. Since 1995 Horstmann is out of business, and all support for ChiWriter has stopped.
