#MEDIA TRANSFER PROTOCOL PORTING KIT WINDOWS 10 WINDOWS#

Support for legacy Windows versionsįor downlevel operating systems, specifically, Windows 2000, Windows 98 and Windows Me, Microsoft has released the MTP Porting Kit. Windows 7's sensor platform supports sensors built into MTP-compatible devices. Changes made to file properties (such as a user rating) on a device can be propagated back to the computer when the device is reconnected. AutoSync is customizable so that the player will transfer only content that meets certain criteria (songs rated four stars or higher, for instance). Additionally, on Windows, MTP-compatible devices support a feature called AutoSync, which lets users configure Windows Media Player to automatically transfer all newly acquired or copied content to devices whenever they are connected. Most MTP-compatible devices do not appear through drive letter assignment in Windows Explorer, instead they will appear as "devices" in Windows Explorer. On Microsoft Windows, MTP is supported in Microsoft Windows XP if Windows Media Player 10 or later versions are installed. With PTP/MTP, the file size must be known at the opening stage. Instead, modified objects must be reuploaded in their entirety, which can take a long time for large objects. Neither the MTP nor the PTP standards allow for direct modification of objects. This also means that conventional file system recovery tools will be of no use if the drive is corrupted, or crashes.Īs opposed to USB Mass Storage, a number of operating systems do not support MTP out of the box.

In theory the operating system may hide this difference, but this is not the case on Windows or Mac OS. The actual file system is implemented by the device, not by the computer's operating system. Drawbacksīy design, MTP devices (like PTP devices) are not treated as a traditional removable drive. MTPZ, the Zune Extension to MTP specifically denies access to files until authentication has been processed, which is only possible using Windows Media Player 10 or higher. Nothing specific of this nature is in the core standard but the possibility is allowed via Vendor extensions (whereas USB mass-storage does not cater for such extensions). In particular, MTP Initiators may have to provide passwords and other information to unlock files, or otherwise enable restricted capabilities. In case the device maintains a database/index of the content of the disk, MTP saves the cost of re-scanning the entire disk every time the content is modified.Īdditionally, the MTP allows MTP Initiators to identify the specific capabilities of device(s) with respect to file formats and functionality. The storage media is not affected by failed transfers. In this way, MTP works like a transactional file system - either the entire file is written/read or nothing. MTP and PTP specifically overcome this issue by making the unit of managed storage a local file rather than an entire (possibly very large) unit of mass storage at the block level. In practice, therefore, when a USB host computer has mounted an MSC partition, it assumes absolute control of the storage, which then may not be safely modified by the device without risk of data corruption until the host computer has severed the connection. In other words, the USB mass storage class is designed to give a host computer undifferentiated access to bulk mass storage, such as compact flash, rather than to a file system, which might be safely shared with the target device (except for specific files which the host might be modifying/accessing). Ī main reason for using MTP rather than for example the USB mass-storage device class (MSC) is that the latter operates at the granularity of a mass storage device block (usually in practice, a FAT block), rather than at the logical file level. The host connecting to an MTP device is called an MTP Initiator whereas the device itself is an MTP Responder.

Windows 7 and Windows Vista with the Platform Update for Windows Vista also support MTP over Bluetooth. The protocol was originally implemented for use across USB but extended for use across TCP/IP and Bluetooth. The main purpose of this protocol is to facilitate the transfer of media files and associated metadata to/from devices, the management of media files and configuration data on these devices, and to allow the remote control of these devices.
