After receiving the folder information, the recipient checks whether the folder has been transferred locally and determines the file information of the files to be transferred in the folder. When this folder has not been transferred locally, create the folder to be transferred and receive the files to be transferred from the data sending end in the form of a compressed data stream.

In this disclosed embodiment, before sending a file to the data receiving end, the data sending end receives a file transfer request sent by the data receiving end. The file transfer request contains the file information of all files to be transferred in the folder to be transferred. . According to the file transfer request, the data sending end can send all the files to be transferred in the folder to be transferred to the data receiving end without receiving a single file in the process. The file transfer request sends a file and does not need to traverse all the files to be transferred in the folder, thus effectively reducing the file transfer time.

In this disclosed embodiment, the file attribute information includes file size, file type, file location in the folder to be transferred, and other information. When transferring files, the files can be transferred based on the order information of the files to be transferred. For example, the folder contains multiple files to be transferred, including a first file to be transferred, a second file to be transferred, and a third file to be transferred. The transmission order of the files can be determined as follows: the first file to be transferred, the third file to be transferred, and the first file to be transferred.

Figure 3 is a flowchart 3 of a file transmission method according to an exemplary embodiment. As shown in Figure 3, it includes:

Step 30: The data sending end establishes a communication connection with the data receiving end;

Step 31: The data sending end prepares and sends the target information of the folder to be transferred, and establishes a compressed data stream;

Step 32: The data receiving end sends a file transfer request to the data sending end and receives the file to be transferred; the file transfer request contains breakpoint information;

Step 33: The data sending end prepares the real file to be transmitted that needs to be sent based on the received data breakpoint information, and generates the corresponding temporary file;

Step 34: The data sending end sends temporary files and real files to the data receiving end;

Step 35: The data receiving end receives the real file. If the data sending end sends the real file from the breakpoint, the data receiving end can receive the transmitted file at the breakpoint according to the breakpoint information and obtain the entire file; if the data sending end If a complete real file is sent, the transferred file can be received as a whole. During the receiving process, if the reception is not completed and is interrupted again, step 32 can be executed again to send a file transfer request to the data sending end.

This application only needs to send the information of the folder itself to the data receiving end, without the sub-file information of the folder, and can execute the download request on the data receiving end and start the transmission of the folder.

When the folder contains multiple files, you only need to request the data sending end once to write all the sub-files in the directory, and decompress them in real time on the data receiving end. There is no need to perform a request for each file, and you can also avoid similar Slow start in TCP protocol causes the problem of low transmission speed.

This application can decompress the data in real time at the data receiving end, temporarily store the completed files that have not been transferred, and record the file location. When the data receiving end requests the file, it will notify the data sending end of the unfinished file size and location, and the data sending end will notify the data sending end according to the receiving end. To the relative position of the file, find the corresponding position of the corresponding file at the data sending end.

This application generates a temporary compressed file before sending the compressed stream of the file. The name of this file can be based on the next file name to be sent by adding letter symbols, etc., and characters that cannot be used in the real file are used as prefixes to prevent and folder The real name is repeated, and the temporary file can also be associated with the file to be sent. The data receiving end can determine whether this file is a real file or a temporary file that records the next file information through the same rules. The information of this temporary file includes the location, size of the next file, breakpoint resumption and other related information. When the data receiving end receives this file, it can parse the information, calculate the progress based on the size, and perform a resumable transmission operation on the information that can be resumed at a breakpoint.

The file transmission method proposed in this application can effectively reduce network requests, save transmission time, improve transmission speed and transmission success rate, while still supporting breakpoint resumption and progress calculation.
