I was playing with my REGISTERED FILE TYPES setting this morning, and I accidentally messed up my FILE FOLDER settings. When I double click any folder, windows explorer opens a search windows for me instead of opening up the folder contect. I right clicked the folder and I saw the OPEN option wasn't on top of the command menu list (seach option was on top of the list). Well that means OPEN option isn't my default command when I double-click a folder, am i right?. I went to tools\folder options\file types\advanced\edit file types and I couldn't find the OPEN command there. I edited one myself and now I can open the folder content but in a new windows. The "open each folder in the same window" option in tools\folder options\general is ticked. So how can I change it back?
