Abstract
Communications systems and methods for minimizing file corruption when communicating between a device and a host are provided. To initiate a file transfer section, a host can transfer data to a device on a primary communications channel. The device can then temporarily store the received data in a memory circuit until a command is received indicating that the file has been completely transferred. In order to avoid interfering with the data transfer, the host can provide such a command to the device on a sideband communications channel. Upon receiving the command, the device can integrate the received data into its file system by transferring the data from the memory circuit to a more permanent storage component. If the communications interface is disconnected before such a command is received, the temporarily stored data can be considered incomplete and can be deleted.
