 :: It seems BLEND is currently the only file type where dnd is truly supported. This could give a hint where to look into the source and add more types.

+A simple test of opening a dropped file with notepad:
+  char processFile[255];
+  if (ddd->dataType == GHOST_kDragnDropTypeFilenames) {
+          GHOST_TStringArray *stra = ddd->data;

+            strcat(processFile, stra->strings[a] );
+            system(processFile);
+ ...
+ }
+Notepad will open with dropped file. Blender will hang and possible crash if Notepad is not closed.
+So, either the dropped files need to be processed right away or that part must be made independent using fork or create process ...
