DRS_Aok by Ykkrosh is a Tool for viewing and extracting files from DRS files. DRS files are the standard format for data files containing graphics, sounds, etc. If you look in your data folder, you will find many such files, eg. graphics.drs ( which contains image files ), interfac.drs ( containing interface graphics ), gamedata.drs ( containing random maps ) etc. These drs files contain mostly SLP's which store a particular graphic.
