Flat File Source Editor (Connection Manager Page)
Use the Connection Manager page of the Flat File Source Editor dialog box to select the connection manager that the Flat File source will use. The Flat File source reads data from a text file, which can be in a delimited, fixed width, or mixed format.
A Flat File source can use one of the following types of connection managers:
A Flat File connection manager if the source is a single flat file. For more information, see Flat File Connection Manager.
A Multiple Flat Files connection manager if the source is multiple flat files and the Data Flow task is inside a loop container, such as the For Loop container. On each loop of the container, the Flat File source loads data from the next file name that the Multiple Flat Files connection manager provides. For more information, see Multiple Flat Files Connection Manager.
