Embodiment Construction
[0020] Please refer to figure 1 , Which is a schematic diagram of a system 100 according to an embodiment of the present invention. Such as figure 1 As shown, the system 100 includes a server 110 and an electronic device 120. The electronic device 120 is connected to the server 110 through a network (for example, the Internet), and the server 110 includes at least a processor 112 and a storage device. The unit 114 and the storage unit 114 store multiple sets of program codes 116, and the processor 112 is used to execute a part of the multiple sets of program codes 116 to control the operation of the server 112. It should be noted that although figure 1 Only a few components in the server 110 are shown, but those skilled in the art should understand that the server 110 also has many peripheral components to work with the processor 112, and the storage unit 114 may include multiple identical / different components. For the storage chip, since the main spirit of the present inventio...

The invention discloses a file upload and download methods and an associated server. The server includes a processor and a storage unit, the processor arranged to control operations of the server. The storage unit is arranged to store a program code. When the program code is executed by a browser, the browser performs the following steps: receiving an upload command, and copying a file corresponding to the upload command to a virtual file system provided by the browser; partitioning the file in the virtual file system into a plurality of portions; sequentially uploading the plurality of portions to the server via the network, and recording an upload progress of the file in real time; and when the upload of the file is interrupted and the file is re-uploaded, directly uploading the remaining portions of the file that have not yet been transmitted to the server according to the recorded upload progress. With the invention, it is possible to automatically start from the portions of the file that have not yet been uploaded / downloaded after the file upload / download interruption, without having to re-upload / download the entire file.
Description
Technical field [0001] The invention relates to a file upload / download method, in particular to a resuming method. Background technique [0002] When a user uses a browser to upload files to a remote server or download files from the server, if the file upload / download is halfway, the network is disconnected or the browser is accidentally closed, the user needs to reopen the file folder to find the need The uploaded file or find the location of the file to be downloaded, and the file needs to be re-uploaded / downloaded entirely, which causes confusion for users and excessive consumption of network bandwidth. Summary of the invention [0003] Therefore, one object of the present invention is to disclose a file upload / download method and related server, which can automatically start from the part where the file upload / download is not completed after the file upload / download is interrupted, without re-uploading / downloading. Download the entire file to solve the problems described in ...
