Help My Files -- changing order of sub-files

[fried chicken]

On the My Files screen, I see various sub-files (kindle, ScreenCapture, documents, and far down the list, DCIM).
I use DCIM a lot, so I'd like to move it to the top of the list. How can I do that?

as soon as i created a new folder, DCIM moved to the top of the list !!
(it'd been weeks since i added a folder)
