Abstract

Embodiments of the invention provide a file downloading method and apparatus. The file downloading method comprises the steps of creating a target file for a to-be-downloaded file, dividing the to-be-downloaded file into data segments, and allocating the data segments to a plurality of threads for downloading, wherein each data segment has initial position information; opening the target file by the threads and setting a file pointer in a writing position corresponding to the initial position information of the data segment in charge of downloading; and downloading the data segments by the threads and writing the downloaded data segment into the target file from the writing position. According to the file downloading method and apparatus provided by the embodiments of the invention, the file can be downloaded through the threads and written in the target file, so that the downloading is smoother and the downloading experience of users is improved.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a file downloading method and device. Background technique [0002] With the increasing progress of the Internet industry, users can download a wealth of resources through the Internet. For example, more and more users download network video files locally through broadband, and then copy them to mobile devices such as mobile phones and PADs for viewing. Due to the continuous increase of such user demands, the download technology is also continuously developed, which can be roughly divided into two methods: single-threaded and multi-threaded. In order to increase the download speed, multi-thread download is usually used. Specifically, the file is first divided into multiple file fragments, and then the file fragments are downloaded to the local through multithreading, and the multiple file fragments are merged into the original file after the download operation of all fragm...
