Example Embodiment

[0029] Embodiments of the present invention: a method for previewing files, comprising the following steps:

[0030] S1, the user triggers a preview file request;

[0031] S2, the conversion server downloads the file to be previewed from the storage device;

[0032] S3, convert the downloaded file into corresponding preview information and send it to the cache server;

[0033] S4, read the preview information from the cache server and display it.

[0034] In the above method, the method further comprises: directly querying the cache server whether there is preview information of the file to be previewed, and if there is preview information of the file to be previewed in the cache server, then directly reading the preview information, thereby omitting The conversion server downloads the file from the storage device and converts it into preview information, which saves a lot of network resources.

[0035] In the above method, step S3 further includes: analyzing the format typ...

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 ...
