Sticking my neck in here from a bunch of great answers, but I do want to point out one other dynamic. I use both Lightroom AND Bridge but I use them for different purposes. I use LR when I've gone of vacation and have taken hundreds and hundreds of photos and I want to keep them and refer back to them etc. However, if have taken a couple of photos at a friends birthday party where I've no real intent of keeping all of the images and only want to quickly look at them so I can make copies of the one's I might want to send (or something like that), I'll open the images in Bridge, play keep and toss there, adjust the images that need adjustment, resize to send via email and send them off. I may or may not want to keep them. So Bridge and LR are two different applications with two different functions. Keep in mind that if you have an image in LR and then outside of LR display the images in Bridge and make some adjustments in PS, when you go back to LR and look at the same images, LR will tell you that the image(s) were adjusted outside of LR, do you want to keep the new adjustments or revert back to the state that the images were last in in LR. Simply, you can go from LR to PS and back but if you go from LR to Finder/Explorer to Bridge to PS, that's a route that LR is not fully happy with. Lastly, if you want to change the folder's names in LR to better state where you were or what you were doing, be sure to do that WITHIN Lightroom, not the Finder/Explorer. The latter is guaranteed to waste a day to fix it back (personal experience). Let us know if any of this helps you
