If using a Mac computer, additional software is required in order to transfer files.
Connect the device to a computer using the supplied USB cable.
If necessary, touch and hold the Status bar (area at the top of the phone screen with the time, signal strength, etc.) then drag to the bottom.
The image below is merely an example.
Tap the USB icon then select Media Device (MTP).
Launch File Explorer or Windows Explorer.
Using the computer keyboard, press Windows+E (+E) keys.
Alternatively, right-click Start then click File Explorer or Windows Explorer.
Using File Explorer or Windows Explorer, navigate: SAMSUNG-SM-J100VPP > Phone.
If the device is not shown Enable MTP.
If a microSD card is present, files can be transferred to that location by navigating: SAMSUNG-SM-J100VPP > Card.
Use the computer to copy video or image files into the folder (e.g., DCIM\Camera).
