A method selects a folding program for a job to be carried out on a folding system, the job being provided with a job specification. The method includes calculating a fold program and an associated fold configuration based on the job specification, resulting in a set of configuration properties. The method further includes evaluating the fold program to check whether the associated fold configuration properties satisfy a set of configuration conditions. A folding system for folding a job, a printer driver, a computer program and a computer-readable medium for carrying out the method are also included.
