Click the file preview and set the markers against the ruler to
define the file column properties. The orange arrow helps you refine the
position.
The Field Separator and
Marker Position fields are automatically
filled with a series of figures separated by commas.
The figures in the Field
Separator are the number of characters between the separators, which
represent the lengths of the columns of the loaded file. The asterisk symbol means
all remaining characters on the row, starting from the preceding marker position. You
can change the figures to specify the column lengths precisely.
The Marker Position field
shows the exact position of each marker on the ruler, in units of characters. You can
change the figures to specify the positions precisely.
To move a marker, press its arrow and drag it to the new position. To remove a
marker, press its arrow and drag it towards the ruler until a
icon appears.
