What is Media Transfer Protocol (MTP)?
MTP is a feature built into the HTC EVO™ 4G. It doesn't require extra software.
After you plug your HTC EVO 4G into a computer, it automatically connects using MTP.
Your HTC EVO 4G then behaves and installs as a storage device, and you can access the memory card and phone storage.
How does the memory card work?
The memory card is the main storage for your HTC EVO 4G. Your HTC EVO 4G also has 1GB internal storage.
Captured images or video automatically save to the memory card.
All Internet and application downloads, Bluetooth® file transfers, and most media types automatically save to the memory card as well.
Your HTC EVO 4G supports microSD cards up to 32GB.
Sprint recommends storing data to your memory card so you can easily transfer the card to another device.
Your data is safer if you need to troubleshoot your HTC EVO 4G.
