The first embodiment is as follows:
fig. 1 shows a schematic flow chart of a first file transfer method provided in an embodiment of the present application, where the embodiment is mainly described from a mobile device side, where the mobile device includes a mobile phone, a usb disk, and the details are as follows:
step S11, after establishing connection with the PC terminal, obtaining the version information of the operating system of the PC terminal;
in this embodiment, the mobile device establishes a connection with the PC terminal through a USB cable, and after the connection is established, obtains the os version information of the PC terminal, where the os version information includes an os version number and an os name installed in the PC terminal. Of course, if a plurality of operating systems are installed on the PC, the operating system version number, the operating system name, and the like currently in communication with the mobile device are acquired.

Wherein the first specified version information includes at least one operating system version information. When the first specified version information comprises a plurality of operating system version information, if the operating system version information of the PC end is the same as any one of the operating system version information, the operating system version information of the PC end is judged to be the first specified version information. Preferably, the first specified version information is a windows 10 version, or a version above windows 10.
In this step, the MTP protocol specifies input parameters and output parameters, and the mobile device further defines a copy object (CopyObject) and a cut object (MoveObject) supported in the MTP protocol specification, so that the PC can perform corresponding copy operation and cut operation according to the input parameters and the output parameters of the MTP protocol specification and the defined copy object and cut object. The input parameters include the following information: data type, source address, output parameters include the following information: a destination address and a storage location.
In the embodiment of the application, after the connection with the PC end is established, the os version information of the PC end is acquired, and if the os version information of the PC end is the first specified version information, a first operation set is sent to the PC end, where the first operation set includes a copy object and a cut object supported by the MTP protocol, and the first operation set is used to instruct the PC end to perform a corresponding copy operation or a corresponding cut operation according to the copy object or the cut object supported by the MTP protocol. Because the operation set comprising the copy object and the cut object is sent to the PC end after the operation set is connected with the PC end, the interaction with the PC end after one operation is executed is avoided, and because the content included in the operation set is related to the version information of the operating system of the PC end, the copy object and the cut object included in the operation set can be ensured to be matched with the version of the operating system of the PC end, thereby improving the operation success rate of the copy operation and the cut operation and reducing the data loss.
Optionally, there are various ways for the mobile device to obtain the os version information of the PC, for example, obtaining the os version information by inputting the os version information of the PC into the mobile device by a user, or sending the os version information by requesting the PC. When sending the acquisition by requesting the PC side, the step S11 includes:
a1, requesting the version information of the operating system at the PC end through the USB protocol;
a2, receiving the version information of the operating system sent by the PC terminal.
In the above-mentioned a1 and a2, when the mobile device establishes a connection with the PC terminal through the USB cable, the mobile device requests the os version information of the PC terminal through the USB protocol, and the PC terminal sends the os version information corresponding to the os currently communicating with the mobile device to the mobile device.
Optionally, if the operating system of the PC includes a customized copy object and a customized cut object, the mobile device sends a priority setting instruction to the PC, where the priority setting instruction is used to instruct the PC to set different priorities for different scenes: when a copy operation or a cut operation between files (or folders) of the mobile device is executed, setting the priority of a copy object and a cut object which are supported by the MTP protocol and comprise the first operation set to be higher than the priority of a self-defined copy object and a cut object which are contained in an operating system at the PC end; when the copy operation or the cut operation between the files (or the folders) of the PC end is executed, the priority of the copy object and the cut object which are set to be supported by the MTP protocol and comprise the first operation set is lower than the priority of the self-defined copy object and the cut object which are set to be supported by the operating system of the PC end. By setting different priorities for different scenes, the successful execution of the copy operation and the cut operation of the corresponding scene can be ensured.
Fig. 2 shows a schematic flowchart of a second file transmission method provided in an embodiment of the present application, and in fig. 2, the file transmission method further includes:
step S13, if the os version information of the PC is the second specified version information, sending a second operation set to the PC, where the second operation set includes an android native copy object and a native cut object, the native copy object and the native cut object are different from the copy object and the cut object supported by the MTP protocol, and the second operation set instructs the PC to execute a corresponding copy operation or a cut operation according to the native copy object and the native cut object.
Wherein the second specified version information includes at least one operating system version information.
Preferably, the second specified version information is a windows 7 version, or a version below windows 7 or an operating system version corresponding to other non-first specified version information.

receiving feedback information which comprises operation failure and is sent by the PC end, prompting a user to input the version information of the operating system of the PC end, and taking the version information of the operating system of the PC end input by the user as the acquired version information of the operating system of the PC end.
In this step, if the PC fails to perform the copy operation or the cut operation, sending feedback information including the operation failure to the mobile device, the mobile device prompting the user to input the os version information of the PC, and after the user inputs the related information, taking the related information input by the user as the acquired os version information of the PC. Because the operating system version information is input by the user, the accuracy of the operating system version information of the PC side acquired by the mobile equipment can be ensured.
