If you use Adobe Bridge or Picasa, read on.
If you don't use these programs, jump ahead.
As you know, you don't have to import your photographs when using Bridge or Picasa.

You have to import them.
As described, Lightroom doesn't import your photograph files.
• The locations of the files in My Pictures or Pictures.
• The metadata and previews (previews) from the files.
