How to move images and video to SD Card? How to move images and videos from internal storage to SD card in Samsung Galaxy S7?

I saw advice to go to 

My Files -&gt; Images (or other) -&gt; Options -&gt; Select -&gt; All 


then move. But I can't accept this advice because it looks like flatten directory structure, which I need not to.

UPDATE

I want to move files which are created by camera. 

UPDATE 2

I want BOTH:

1) make camera put NEW images and videos to new location

2) make OLD images be located in new location and be seen by gallery

UPDATE 3

So I expect answer suggest either automatic solution, or fully defined manual solution. For example, if solution requires moving files, it should specify BOTH source AND destination directories.
Yes, your advice flattens the directory structure.  

Therefore the only thing you can do is:


Go to My Files -> My Device.
Navigate to the files/folders you want to move
Select the files and folders you want to move
Hit More -> Move
Select the destination
Hit Done
Repeat steps 2 - 6 until you are done.


Files from the Camera app are located at DCIM/Camera/

For changing the default location of photos and videos, go to the Camera app's settings and change the default location.
