Do formats developed by third parties work with ArcGIS Data Interoperability?
No. Only formats that ship with ArcGIS Data Interoperability are supported. If other formats are needed, then the supplemental license FME for ArcGIS – Format Pack for ArcGIS Data Interoperability must be purchased from Safe Software. Once this is installed, the ArcGIS Data Interoperability gains the full functionality of the FME ESRI Edition.
