Description
The multifile feature connection file (.mfc) specified does not exist or is invalid.
Solution
Verify that the pathway to the multifile feature connection file is specified correctly. A pathway to a .mfc file should be formatted such as c:\MyProjectFolder\MyMultifileFeatureConnection.mfc.
If you suspect you have made invalid manual edits to your multifile feature connection, or have deleted it by accident, try re-creating the connection using the Create Multifile Feature Connection tool.
