Use folders to organize images in the new Media Gallery. As the number of media assets increases, folders make it easier to locate and manage existing assets in your media gallery.
On the Admin sidebar, go to Content > Media > Media Gallery.
Click Create Folder.
If you want to create a subfolder, select the parent folder before clicking Create Folder.
Enter the new folder name and click Confirm.
Deleting a folder causes the removal of all the images within that folder.
On the Admin sidebar, go to Content > Media > Media Gallery.
Select the folder to be deleted.
Click Delete Folder.
To confirm the folder deletion, click OK.
