Photoshop Elements has had a Folder View for some time. But in earlier versions it was a bit clunky and had some bugs that were problematic. Consequently, I did not use it much.
However, in PSE 11 the folder view was improved significantly. I think it can be a very useful tool for those of you who have organized your folders into well thought out folders and sub-folders. Even if your folder system does not have a lot of thought put into it, it can be quite helpful when you need to know the physical location or path to a particular group of photos. An example of such an occasion is when you are uploading a series of photos to somewhere like Costco to order prints. At some point in the process you need to navigate to the actual location of the pictures.
I have made a short video that explains the how this view works. It is the top item on my Video Tutorials page of my website. Here is the link to that page.
As you can see, the videos on this page have become dated and were made with earlier versions of Elements. However, they are still useful today. Sometimes it is primarily only the dark background that is the main difference. I have removed some, and will be adding new ones and even updating the older ones on the page soon.
Please let me know if these videos are at all useful, and what other topics you would like see covered.
