I keep all my photos on an external hard drive (F:) and use LR6 on my laptop. Occasionally LR6 shows a number of "?" in the folders section normally indicating that I forgot to attach the HD. Once I attach the HD, and restart LR, everything works. Sometimes I get a "?" and simply need to use the "find" function to show LR where the folders/files are located. This time, my whole LR file structure is showing "?". When I right click and chose "find", then point to the F: drive, the 'puter shows two complete sets of matching folders. When I select one of them, an option pops up to "Merge" the two same named folders. This one has me stumped... Anyone else have this situation?

I'm not sure what this means. Can you show us a screen capture?
In the long run, the problem you are having would go away if you renamed your external drive from F: to some letter near the end of the alphabet like W:
I'll try a screen capture once I get home. Will also try renaming the drive.
