Fig. 3.3-1 BINGO matrix files

These files need a lot of disc space in case of big blocks. Therefore it may make sense or even be necessary in some cases to assign these files to specific disc areas, with help of the BINGO PROJECT file. This can be applied for the BINGO files listed in Fig. 3.3-1. Further files are declared to be only scratch files and cannot be assigned in any way.
