Sets the format of the file that a dataport reads from or writes to.
Dataports
Variable (default)
Read/write in a variable length format
Fixed
Read/write in a fixed length format
If FileFormat is set to Variable, you must also set the FieldEndDelimiter Property, FieldStartDelimiter Property and FieldSeparator Property to define how fields are separated.
If FileFormat is set to Fixed, these properties are ignored, and the StartPos Property and Width Property must be set to define the placement of the fields in the imported line.
