I love using Picasa for viewing and editing my photos. What I don’t love is that it automatically scans and imports tons of unwanted photos by default. This creates a ton of clutter and makes it difficult for me to find the actual photos I want to work with. Fortunately it is easy to prevent Picasa from scanning folders.
First, open Picasa. Navigate to Tools then Folder Manager…
From there, all you need to do is select all of the folders in the Folder List and select Remove from Picasa.
Now you can use Picasa without the added clutter caused by auto-scanning and importing.
