Notes about the FMW 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 FMW file type is primarily associated with 'FME Workbench' by Safe Software Inc.. FME Desktop is a flexible and powerful spatial ETL toolset that makes it easy for you to translate, transform and integrate spatial data in any format or application.
