As shown in Stack [A] above, the top flap is slightly shorter than the other folds below which
are of uniform size. If this is not desirable, the folding job can be set to calculate how much
paper is needed for the last fold to ensure that the top flap is the same length as the other
folds below, with folded surfaces of shorter length hidden in the stack. The folds of the
paper remaining before the final full-length fold are "adjusted" to create shorter sections
that will be covered by the top flap, so that the stack has a neat and uniform appearance.
These adjusted folds can be done for either long folds or file folds as shown above.

cover the shorter adjusted folds below.
! Stack [D] is a file fold (the first fold is a valley fold). The folds are adjusted at
