Now we get to the point where you can decide which folders and subfolders are to be scanned by Picasa.
Now, let's check off a few folders that we want scanned.
We click "NEXT" to initiate the scanning and then we are informed the scanning is about to begin.
Now we click "FINISH", and the fun part begins! This part is really exciting because you watch Picasa scan the folders, and you now see the interface you will be using to view your photos.
