Notes about the WO 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 WO file type is primarily associated with 'WebObjects' by Apple Inc.. WebObjects is a rapid application development environment with web services, data access and page generation capabilities. The .WO project is not yet deployed.
