Go to GStudio8 -> data -> options.scr, open it with a text editor, find EXCLUDE_RESOURCE = "WRS;TMP;AVI;MPG;MOV;DLL;C;H;XML;LOG;TXT;PNG"
, for me personally this is already correct (maybe I changed it earlier or cause of new version, cannot remember). Also kindy funny that you can remove wrs from it, so you can have wrs files within your wrs files.
