Abstract

The invention provides a method, a device and a system used for compression and uncompression and based on a cloud compression file, which solve the problems that file compressing rate is not low, and files are limited to exchange and share on internet. The method for compression includes that a cloud compression request is triggered; a client conducts automatic compression on local file data to be compressed according to the cloud compression request and uploads compressed data as cloud compression data to a server to be stored; the server produce a corresponding cloud compression file according to the cloud compression request and transmits the cloud compression file to the client, and the cloud compression file comprises file identification information of the cloud compression data; and the server builds a mapping relation between the cloud compression data and the cloud compression file. The method, the device and the system can convert a file of any capacity into the cloud compression file, compression rate is reduced to less than 1%, and space is hardly occupied.

Description

technical field

[0001] The present invention relates to compression and decompression technology, in particular to a compression method based on cloud compressed files, a decompression method based on cloud compressed files, a compression device based on cloud compressed files, a decompression method based on cloud compressed files A compression device and a cloud-based system for compressing files. Background technique

[0002] With the development of Internet technology, the speed of network broadband is getting faster and faster, and people use the network to exchange and share files more and more, such as using e-mail and instant messaging tools.

[0003] However, in many cases, there are still many inconveniences for people to share files, which restricts the exchange and sharing of files on the Internet. E.g:

[0004] Send a 25M file to a forum for everyone to download, but the forum only supports 5M attachments;

[0005] Email a file with a size of 35M to others, b...

Embodiment Construction

[0086] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0087] The traditional file compression rate has not improved much over the years. It is very rare for ordinary files to achieve a compression rate of 50% or 40%. It is rare to reach 20%-30%. Very few files can be compressed to reach 10% or a few percent. the compression rate.

[0088] The present invention proposes a new compression method, which can automatically compress local files and upload them to the network server for storage, and the server generates cloud compressed files corresponding to the cloud compressed data and then sends them to the client, and the client user can send the cloud compressed files to other users of client users. By clicking the cloud compressed file, the user can directly download the correspondi...
