MTP (Media Transfer Protocol) mode is a connection mode for transferring files between a computer and a smartphone. It is different from other connection modes such as USB Mass Storage, because it allows the computer to access the internal memory of the device, instead of just the external storage. This means that files can be transferred directly from the device, instead of having to be copied to an external storage device first. Additionally, MTP mode allows for more efficient file transfers, as it can transfer multiple files at once.
