I last used Lightroom 2 several years ago, and have been using Bridge to keep track of my files. I got into the habit of copying some files from one project folder to another. While they are duplicate files, I found it useful to operate in this fashion.
I just installed LR4, and decided to make a brand new catalogue and import all of the picture files from 3 different HDD's on which I keep my photos. However, LR4 did not import the duplicate files mentioned above, and I could not find anywhere to tell LR4 that I wanted the duplicates imported as well.
How can I go about importing the duplicate files? There are too many for me to go looking for them individually, and I would like to somehow sync each of the HDD's and have the dupes imported.
