Any app on your phone with the WRITE_EXTERNAL_STORAGE permission may create files or folders in this location. There are some default folders such as Android, DCIM, and Downloads present in most mobiles. The following screenshot shows the contents of the /storage/self/primary location:
Digital Camera Images (DCIM) is the default directory structure for digital cameras, smartphones, tablets, and related solid state devices. Some tablets have a Photos folder that points to the same location. Within DCIM, you will find photos you have taken, videos, and thumbnails (cache files). Photos are stored in /DCIM/Camera.
