<span style=color:red>(-)</span> Windows does not assign [[drive letter assignment|drive letters]] or [[Universal Naming Convention|UNC]] paths to MTP devices because it does not natively expose them as [[virtual file system]]s. Without drive letters or UNC paths, MTP-unaware software cannot access directories or files on these devices. The user has to switch to an MTP-aware application, or else [[workaround|work around]] by using an MTP-aware application such as Windows Explorer to copy or move the file to a file system that the application can access.

One specific concern is that [[antivirus software]] on the host computer may not be aware of MTP devices, making them potentially less secure than mass storage devices (although if files on MTP devices are copied or moved to the host before use, MTP-unaware antivirus software will have a chance to scan them). Antivirus scanning might also be impractical due to blocking regular use of the device.
