I have some videos in folders and some aren't in folders so when I want to arrange by "date modified" the ones without folders stay in a bunch at the top in order and the ones in folders stay together. I want to arrange ALL the folders by "date modified" without them splitting by "Type".
You should use a Search result in this case. At the root (start) of your video folder, type in
Then change the Search Result to details view. Then you can sort by Date modified.
You can also tack on to the Search command
