Returns the destination file name pattern used to name the file during writing.

When the Dest Data Definition is a File Definition, you can use this property to modify the name of the output file after mapping.

The filename property is a pattern - therefore you can set it directly to the name you desire, or you can include Tags within the name.

Tags will be resolved when the file is being saved.

Declaration: property FileName: string

An example of its use, follows.

procedure OnMapEvent(var Value:Variant);
begin
//Result is the name of the file that is the source of the map
Value := Dest.FileCon.Filename;
end;
