Some of you might be curious about my request above, which is to replicate what's available in OneCommander. If you have a long catalog, such as a texture catalog, you can view them side-by-side in OneCommander. On the left side, you'll see a list of your catalogs, and on the other side, you'll see the contents of the selected folder as thumbnails.
You can do this in Dopus with a simple command line command, go openindual If you want to see the contents of the folder in the destination tab.
Or you can use the script above from @lxp if you want to see the content in a specific layout.
Personally I prefer to use Dopus for things like this because Dopus has more features, one of which is in Dopus you can enlarge the image to see the details just by clicking and holding the image in the viewer pane and it is very, very useful.
Or you can use another script from @dasota to see the contents of the folder.
