2.2.8.2 External Connection Files
An external connection file specifies an external connection in a separate file (external to the workbook). An external connection file enables managing connection information separately from a specific workbook and sharing it among multiple workbooks. It is used for creating a new external connection in a workbook or for restoring a lost connection. The stConnectionFile field of the BrtBeginExtConnection (section 2.4.80) record specifies a path to an external connection file.
