Notes about the WPW 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 WPW file type is primarily associated with 'PerfectWorks' by Corel. PerfectWorks was sold by Novell to Corel and is now part of the WordPerfect Suite.
