In Blurb trying to upload an album that I have prepared in Adobe, but I can't find any Adobe files that way.

I am in Blurb, trying to upload an album that I have prepared in Adobe ELements 10.  To upload I need to navigate in my computer to whatever Adobe folder has the album, but I can't find any Adobe files that way.  So I wanted to save the album to
an external drive where I could be sure to find them for the upload

But when I tried to copy the photo album, the dialog box said that the photos will be deleted from the main program.  I didn't like the sound of that, so I chose "Backup" which seems to have copied everything from Adobe to my eternal drive, not just the photo album that I want.  To make matters worse, but exported folder named for my photo album is not the group of photos that I assembled in Adobe.

How do I upload directly from Adobe the program on my hard drive so I can be sure it is the correct assemblage of photos?
