What is a DSR file?
Server recipe created and used by Call of Duty: Modern Warfare 3 (CODMW3), a first-person shooter game that features political war gameplay; contains a set of match rules that are assigned to a specific map featured on a CODMW3 dedicated server.
A DSR file is used along with a .DSPL file to configure game rules of a CODMW3 dedicated server. You can open and edit the DSPL file with a text editor such as WordPad or Notepad, however, if you edit a recipe file during a session the changes will occur in the next map.
NOTE: Default DSR files, such as Team Deathmatch, Drop Zone, and Domination, for the Steam version of CODMW3 are located in the Modern Warfare 3 directory in the "admin" folder.
