Thanks Robert John. But in my Pacific install the SCENEDB/inf/scenery does have a file list. But, in my WWI install, I had installed some new item in the SCENEDB/inf/scenery folder and removed the filelist that was present so the sim would create a new one (filelist) when I re-started the sim. However, no new file list was generated as it had in the past when I did add to the inf/scenery folder.?
