Problems solved by technology

[0008] For differential upgrade, only the differential data is downloaded. The disadvantage is that the file size is large. However, for the aforementioned situation, if there are many versions for the same product, first of all, because the files of each version need to be consistent, then as the version A large increase, the number of corresponding files in various versions has increased, resulting in more and more complex logic for maintaining the consistency of files in various versi

Abstract

The invention discloses a program updating downloading method and a program updating downloading device, relating to the technical field of a computer. The method comprises the following steps of storing various data used for updating in an executable file data area and storing list file data in a designated bit position or a data segment of the updating data area; receiving a program updating downloading request of a client-side; according to the program updating downloading request, obtaining and further performing comparison on first list file data of an executable file of a server and second list file data of an executable file of the client-side to judge whether the updating data which are not downloaded exist on the client-side; in the case of the existence, extracting the updating data from the executable file data area and further providing the updating data to the client-side for downloading. With the adoption of the program updating downloading method and the program updating downloading device, all the installation program versions are unique, so that the consistency of file versions is fully guaranteed; and therefore, the file quantity is decreased, the efficiency of seeking the files by the server is guaranteed, the downloading efficiency of the service is improved and the disk storage space also can be saved.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a method and device for program upgrade and download. Background technique [0002] For program upgrades, such as game programs and other applications, there are generally two ways: [0003] One is the whole package upgrade, which is to combine all the files of a program version into the installation package, and then install or upgrade the original version after the terminal upgrade program is downloaded. [0004] The second is differential upgrade. The method is to store the data files in a certain way, form a data file list, and write some information of these data files. The upgrade program of the terminal first downloads the data file list and compares it with the local file to form List of differences, and then download the corresponding data files to upgrade. [0005] However, in practice, the existing technology can make a new version of the product at interva...
