You can use an utility such as Disk Usage & Storage or ES File Explorer which will show you graphical information of your storage usage. Once analyzed, you can sort folders by size and try to locate the particular folder. Using a file manager, I would definitely check
/Android/obb folders. The orphaned files and folders are highly likely to be located in one of those. The external SD card storage can be used in any way you please. You can use it as the default storage for photos/videos, you can copy files on it etc.
