Transferring albums and folders from older version of Elements.

Meanwhile, you may take a look at these self-help documents: Import photos and videos in Elements Organizer Move Elements Organizer catalog

The second link is important to understand how to transfer both your photo folders and your catalog to a new computer or drive.

If you install a newer Elements version on the same computer, you don't have to do a backup (even if it's always a good idea), you have to 'convert' the catalog. Remember you can use both versions on the same computer (they are independent) but you need a catalog in the new format, with your own organization data (tags, captions...)

That's what the conversion process is for.
