If this is the one i too have tried, which seems so, i should comment this that this little software is good for nothing. At least in my case. It uses the thumbnail images embbeded in to images. Which is no bigger than the one you see at the folder pane. If you prefer using a fresh thumbnail generated by this, you should be patient enough since it increases the wait time, noticebly,when you right click on a picture. Also, it doesn't recognise as much formats. It is good for nothing, for me.
