To organise high speed films DaVis uses a certain file structure: A film consists of a *.set-file and a folder with the same name as the set file (e.g. film1.set; film1, where film1 contains the individual images)
A group of films is also organized in such a way, here the folder contains the set files and the folders with the film.

The simple routine tests of which level the set file is and stores folder and image names in a struct which is given back (SFM)
