Method and system for previewing file

Abstract

The invention discloses a method and a system for previewing a file. The method comprises the following steps that: 1, a user triggers a file-previewing request; 2, a conversion server downloads the file to be previewed from a storage device; 3, the downloaded file is converted into corresponding preview information and the corresponding preview information is sent to a cache server; and 4, the preview information is read from the cache server and displayed. In the invention, the file to be previewed is converted into the corresponding preview information by the conversion server and displayed to the user in a manner of the preview information, so that blind search operation of the user is reduced, a large amount of search time is saved for the user and a large quantity of precious bandwidth resources are saved for the servers in a network. According to statistics of a large amount of data, the size of general preview information is several K-bits, so that the storage space occupied by the original searched file is larger; therefore, by adoption of the invention, more bandwidth resources are saved for the servers in the network.

Description

technical field [0001] The invention relates to a method and a system for previewing files, belonging to the field of network communication. Background technique [0002] Network disk, also known as network U disk or network hard disk, is an online storage service launched by some network companies. It provides users with file management functions such as file storage, access, backup, and sharing, which is very convenient to use. If a user wants to download a certain target file from a shared file of a network disk of a social friend, he must search from a large number of shared files. [0003] However, in the prior art, if a user wants to find a file in a file shared by a friend's network disk, he can only download the file from the network disk, and then open it to determine whether it is the target file to be found, and if not, download other files. The file open judgment, and so on. In this way, the entire file is downloaded every time and then judged, and the user's ...

AI Technical Summary

Problems solved by technology

[0003] But in the existing technology, the user wants to search for a certain file in the friend's network disk shared file, can only download the file from the network disk, then open it to judge whether it is the target file to be searched, if not, then download other file open judgment, and so on

In this way, the entire file is downloaded every time and then judged. The user's viewing operation is relatively blind, which not only wastes a lot of time for the user, but also wastes a lot of valuable resources of the server in the network.
