- Figure 5 illustrates a structure diagram of an IM client in accordance with the present disclosure.
- Figure 1 illustrates a system structure diagram of a P2P file directory transfer environment in accordance with the present disclosure.
- the system structure is an IM system structure.
- the IM system structure includes multiple IM clients and possibly more than one IM server, although two IM clients and one IM server are illustrated in Figure 1.
- the present disclosure uses the IM system structure as shown in the Figure 1 as an example.
- the IM system structure shown in Figure 1 includes an IM server 10, an IM client 21, and an IM client 22.
- the major functions of IM server 10 may include: authentication and management of an IM client login system, management of user information in the IM system, and forwarding a file when there is a need to transfer the file between IM clients.
- the IM client 21 and IM client 22 can communicate by instant messaging and transfer a file by conventional method.
- An embodiment of the present disclosure improves the IM client and increases a function to transfer file based on a file directory.
- the embodiment also improves the IM server (or any other server in the IM system, such as a relay server) to support the function of forwarding a file directory.
- FIG. 2 illustrates a flowchart of P2P file directory transfer in accordance with the present disclosure.
- IM client 21 When a user intends to use IM client 21 to transfer a file directory and all file folders and files under the file directory to IM client 22, the user can, for example, use a mouse or any other method to choose the file directory to be transferred (or selection of one or more file folders) and drag it into a window for an IM interaction with a target user.
- an operation system where the sending IM client resides can capture such operation and a target of the operation (or the selected file folder), obtain information of the target (or a location, a size, contained files or sub-folders, and other information of the file folder), and transfer the obtained information to the receiving IM client.
- the IM client 21 after receiving the aforementioned information, triggers a file directory transfer event (a corresponding relationship between such operation type and target and the file directory transfer event can be pre-established, or the above operation triggers the file directory transfer event), and triggers a process of file directory transfer according to the event.
- a command button for file directory transfer is pre-established at an interactive IM communication window at the IM client 21. When the button is clicked, a dialog box or an input box is popped up to let the user select or input the file directory. Given the user selected or input file directory, the file directory information is obtained and the file directory transfer event is triggered, and the process of file directory transfer is triggered according to the event.
- the process establishes a P2P connection between IM client 21 and IM client 22.
- Such connection is used in the upcoming file directory transfer, such as by establishing a file transfer protocol (FTP) connection for example.
- FTP file transfer protocol
- the IM client 21 sends a notification message to IM client 22.
- the notification message includes a name of a file folder under the file directory to be transferred and a location of the file folder under the file directory.
- the IM client 22 receives the notification message, and establishes a file folder according to the name of the file folder under the file directory and the location of the file folder under the file directory.
- IM client 22 can establish the file directory and the contained file folders at a default location, or at a user designated location.
- the IM client 21 sends files under a root directory of the file folder one by one to IM client 22.
- the IM client 22 stores the received files under a root directory of the newly established file folder.
- the steps 202-205 are repeated until all files under all file folders and their root directories under the file directory are transferred (by reference to a step 206).
- the IM client 22 establishes an equivalent file directory with the same file directory structure and the same contained files as those at the IM client 21. After completion of the entire file directory transfer, the communication connection between ⁇ client 21 and IM client 22 for the file directory transfer can be disconnected. As IM client 21 knows in advance the information of the file directory (including all files contained in the file directory), when a file is transferred, IM client 21 can determine whether all files under the file directory have been transferred. Otherwise, either the file transfer can be continued or the P2P connection is disconnected.
- the above process shows that there only needs to be one communication connection for the file directory transfer between IM client 21 and IM client 22.
- the process of the file directory transfer utilizes the one communication connection.
- the techniques proposed by the present disclosure saves the cost in establishing the connection and thus improves file transfer performance.
- Another embodiment of the present disclosure can be obtained by improvement of the process as shown in Figure 2.
- IM client 21 after establishing the P2P connection between IM client 21 and IM client 22, IM client 21 can firstly send directory information of the file directory to be transferred (including all contained file folders and a hierarchical relationship between the file folders) to IM client 22.
- IM client 22 can establish a corresponding file directory based on the directory information. Later operations in which IM client 21 sends files are similar as the process described above.
- the notification message needs to carry only the location information of the current file folder in the file directory.
- IM client 22 after IM client 22 receives the notification message, it need not establish a file folder but locates a corresponding file folder in the established file directory, and stores files received afterwards under a root directory of the located file folder.
- IM client 21 can directly use a method for server relay to transfer files under the file directory.
- Figure 3 illustrates a process to use for a relay server to implement transferring files under the file directory in accordance with the present disclosure.
- This embodiment uses an example of IM server 10 as a relay server and IM client 21 as the client of the sender transfer files under the file directory to IM client 22.
- the process show in Figure 3 includes a number of steps as described below.
- the process establishes a communication connection between IM client 21 and IM server 10. The communication connection is used for an upcoming file directory transfer.
- IM client 21 sends a name of a file folder in the file directory to be transferred and location information of the file folder in the file directory, in a form of a notification message, to IM server 10. After receiving the notification message, IM server 10 forwards it to IM client 22.
- IM client 22 After receiving the notification message, IM client 22 establishes a file folder according to the name of the file folder and the location information of the file folder in the file directory.
- IM client 21 sends files under a root directory of the file folder to IM server 10, one by one, and IM server 10 forwards the received files to IM client 22.
- IM client 22 stores the received files in a root directory of the newly established file folder.
- the steps 302-305 are repeated until all file folders under the file directory to be transferred and all files under root directories of all file folders have been transferred (by reference to a step 306).
- a file directory at IM client 22 having the same file directory structure and the same contained files as those of IM client 21 is created.
- the communication connections between IM client 21 and IM server 10, and between IM client 22 and IM server 10, can be disconnected.
- the relay server can have certain memory space to cache information, such as file data transferred by IM client 21, and then forward the cached information to IM client 22.
- IM client 21 can firstly send directory information of the file directory to be transferred (including all contained file folders and a hierarchical relationship between the file folders).
- IM client 22 can establish a corresponding file directory based on the directory information. Later operations in which IM client 21 sends files are similar as the process described above.
- the notification message needs to carry only the location information of the current file folder in the file directory.
- IM client 22 after IM client 22 receives the notification message, it needs not to establish a file folder but locates a corresponding file folder in the established file directory, and stores files received afterwards under a root directory of the located file folder.
- a sending IM client before a sending IM client transfers files under the file directory, it can send information through a request for file transfer to the receiving IM client.
- the information may include a storage space of all files under the file directory and a number of all files under the file directory.
- receiving IM client can determine whether the storage space of the file directory complies with a preset condition of data volume of the file directory, whether the number of files complies with a preset condition of limitation of file number, or whether a device where the IM client locates has enough storage space for storing all files under the file directory, and return a response to the sending IM client upon the determination result as to either accept or refuse the request for file transfer.
- IM client 21 before sending files IM client 21 can compress the files and transfer the compressed files.
- IM client 22 After receiving the compressed files, IM client 22 can decompress the files. It helps to reduce system resources utilized by the file transfer as well as file transfer delays.
- IM clients 21 and 22 may use a third-party compression tool to compress/decompress the files.
- a file compression/decompression function module can be integrated with IM clients 21 and 22. IM clients 21 and 22 can use such module to compress/decompress files.
- the following description uses an example of a specific file directory to detail a process that IM client 21 transfers a file directory to IM client 22.
- Folder 1 (file folder 1) is a root file folder of the file directory. Under a root directory of Folder 1, there are two file folders, i.e., Folder 2 (file folder 2) and Folder 3 (file folder 3), and three files, i.e., File 1, File 2, and File 3. Under a root directory of Folder 3, there is a file, i.e., File 7. Under a root directory of Folder 2, there are two folders, i.e., Folder 4 (file folder 4) and Folder 5 (file folder 5), and three files, i.e., File 4, File 5, File 6. Under a root directory of Folder 4, there are three files, i.e., File 8, File 9, and File 10. Under a root directory of Folder 5, there is a file, i.e., File 11.
- This embodiment is based on the IM communication system as shown in Figure 1, and transfers files under the file directory, a structure of which is shown in Figure 4.
- the file transfer process is described below.
- IM client 21 attempts to establish a P2P connection with IM client 22. If the establishment of a P2P connection is not successful, a connection is established through relay by the IM server. This process uses an example that ⁇ client 21 successfully establishes the P2P connection with IM client 22.
- IM client 21 sends a transfer request message to IM client 22.
- the transfer request message carries information of a total size of the file directory to be transferred.
- IM client 22 determines whether there is enough space locally to store the file directory. If affirmative, IM client 22 returns a response to accept the transfer request; otherwise the file transfer fails and the file directory transfer process ends.
- IM client 21 After receiving the response of acceptance of the transfer request, IM client 21 uses Folder 1 as a first file folder to be transferred, and sends a notification to IM client 22.
- the notification message carries a name of Folder 1 and location information of Folder 1 under the file directory.
- the notification message indicates the location of Folder 1 is the root file folder of the file directory.
- IM client 22 creates a file folder according to the name of the file folder and the location of the file folder under the file directory.
- IM client 21 compresses files, one by one, under the root directory of Folder 1, i.e., File 1, File 2, and File 3, and transfers the files to IM client 22.
- IM client 22 decompresses and stores the files at a root directory of the created Folder 1.
- IM client 21 After completing transferring of files under the root directory of Folder 1, IM client 21 sends another notification message to IM client 22, which carries a name of Folder 2 and its location information under the file directory (such as Folder 1/Folder 2 which represents that Folder 2 is a child file folder of Folder 1). After receiving the second notification message from IM client 21, IM client 22 creates a file folder according to the name of the file folder and the location of the file folder included in the another notification message (in other words, Folder 2 is created under Folder 1).
- IM client 21 compresses files, one by one, under the root directory of Folder 2,
- IM client 22 After receiving the compressed files from IM client 21, IM client 22 decompresses and stores the files under a root directory of the created Folder 2.
- IM client 21 transfers all file folders under the file directory to IM client 22.
- the device where IM client 22 resides stores a same file directory as the one transferred by IM client 21.
- the process of file directory transfer is complete.
- IM client 21 firstly sends the structure information of the file directory (including all file folders and the hierarchical relationship among the file folders) included in the transfer request message to IM client 22.
- IM client 22 creates a corresponding file directory according to the structure information of the file directory.
- the subsequent operations in which IM client 21 sends files are similar to the process described above.
- the sent notification message can include location information of a current file folder under the file directory. For example, before transferring files under the root directory of Folder 2, IM client 21 sends location information of Folder
- IM client 22 needs not create a file folder. Instead it only needs to locate a corresponding file folder from the created file directory, and stores the files received afterwards in a root directory of the located file folder. This can also be utilized for file directory transfer between IM clients.
- the present disclosure also provides a structure of an IM client.
- FIG. 5 shows a structure diagram of a computing device where an IM client resides.
- the computing device includes a processor and a storage that is coupled to the processor to store data.
- the IM client includes a sending module 501 and a receiving module 502, both of which executable by the processor.
- the sending module 501 is used to transfer, one file folder after another, files under a respective root directory of a file folder under the file directory to another client for file directory transfer.
- the receiving module 502 is used to receive a notification message, sent by another client for file directory transfer, including a name of the file folder and location information of the file folder under the file directory, to create a file folder according to the notification message, and to store files received afterwards (or after the notification message) to a root directory of the crated file folder.
- the IM client also includes a file compression/decompression module 503, executable by the processor of the computing device, to compress a file to be transferred by the sending module 501, and to decompress the file received by the receiving module 502.
- a file compression/decompression module 503 executable by the processor of the computing device, to compress a file to be transferred by the sending module 501, and to decompress the file received by the receiving module 502.
- the sending module 501 sends the file after it is compressed.
- one alternative plan for the sending module 501 is that the sending module 501 of the sending IM client firstly sends the structure information of the file directory to the receiving IM client for file directory transfer, and then sends files under a root directory of each file folder under the file directory one file folder after another. Before sending files under the root directory of a respective file folder, the sending module 501 firstly sends a notification message including location information of a current file folder under the file directory, and then sends all files under the root directory of the current file folder.
- one alternative plan for the receiving module 502 is that the receiving 502 of the receiving IM client receives structure information of the file directory from the sending IM client for file directory transfer, and creates the file directory according to the structure information of the file directory.
- the receiving module 502 receives the notification message including the location information of the current file folder under the file directory from the another IM client for file transfer, and locates the file folder under the created file directory according to the notification message, and stores the files received afterwards (or after the notification message) in a root directory of the located file folder.
- Such computer program instructions may also be stored into a tangible, non- transitory computer-readable storage medium that can function in a specific way and boot the computer or any other programmable data processing device such that the instructions stored in the computer-readable storage medium can implement functions as an instruction apparatus.
- the instruction apparatus can realize functions designated by one or more flow processes of the flowchart figures and/or one or more diagrams of the diagram figures.
- Such computer program instructions may also be loaded into the computer or any other programmable data processing device such that the computer or the programmable data processing device can perform a plurality of operation steps to realize functions by operation of such computer.
- instructions performed at the computer or any other programmable data processing device implement functions designated by one or more flow processes of the flowchart figures and/or one or more diagrams of the diagram figures.
