RS is part of a group of formats called Sun Raster Images, developed by Sun Microsystems for use on its UNIX platforms. Similar formats include RAST, RAS and SUN. Files with the RS extension contain bitmaps that were created or processed on workstations or servers developed by Sun Microsystems. They are considered rare and are probably difficult to open via regular image viewers.
The quick and simple way to handle your files is to get a quality piece of software, such as reaConverter. This software is extremely efficient in managing a wide range of batch conversions. As you will soon realize, reaConverter will help you avoid spending countless hours trying to figure out how to convert multiple RS files as once.
