Before using your device’s mass storage capabilities, you need to prepare your device’s data services to synchronize with your desktop or laptop computer. Once you have connected the device to the computer, you can transfer your data to or from the device memory.
Use the USB Cable that came with your phone to connect the phone to a USB port on your computer.
Open the Notifications panel, then tap USB connected.
Tap the connection mode you want to use to connect to the PC. Choose from the following options: Charge only, Media sync (MTP), Internet connection, and Camera (PTP).
When you connect the phone and PC using a USB Cable and set your device’s USB connection mode to Media sync (MTP) or Camera (PTP) mode, you will see one portable device for MTP or imaging device for PTP on the PC. You can copy files to/from the removable microSD card.
