Abstract

The present invention relates to a method and a device for resuming download. The method for resuming download comprises: converting a file incompletely downloaded by a first download tool to a file identifiable to a second download tool, so that the second download tool resumes downloading the incompletely-downloaded file, wherein the first download tool and the second download tool are different download tools. The present invention implements relay download of different download tools, and can be applied to file download, so as to avoid wasting network resources and time of users.

First claim

What is claimed is:

1. A method for resuming file download, comprising:
generating a mapping table for completely-downloaded and/or incompletely-downloaded files and their storage addresses;
using the mapping table to look up whether a file incompletely downloaded by a first download tool exists upon executing resumed downloading of the incompletely-downloaded file, and prompting the user whether to perform file format conversion upon determining the incompletely-downloaded file already exists;
responsive to the user indicating to perform file format conversion, converting the incompletely-downloaded file to a file identifiable by a second download tool, so that the second download tool resumes downloading the incompletely-downloaded file, wherein the first download tool and the second download tool are different download tools and their respective identifiable files are different.

2. The method for resuming file download of claim 1 , wherein
converting the file incompletely downloaded by the first download tool to the file identifiable by the second download tool comprises the step of, upon executing the incompletely-downloaded file, triggering converting the file incompletely downloaded by the first download tool to the file identifiable by the second download tool.

3. The method for resuming file download of claim 1 , wherein the second download tool and the first download tool use a downloading mode of the same network transmission protocol for file download, and use different file formats to store the incompletely-downloaded file.

4. The method for resuming file download of claim 1 , wherein the second download tool and the first download tool use downloading modes of different network transmission protocols for file download, and use different file formats corresponding to the downloading modes of the different network transmission protocols to store the incompletely-downloaded file.

5. The method for resuming file download of claim 4 , wherein after converting the file incompletely downloaded by the first download tool to the file identifiable by the second download tool so that the second download tool resumes downloading the incompletely-downloaded file, the method further comprises:
obtaining a preset resource list which comprises a resource identifier and a resource obtaining address of the same resource in the download tools performing file download by using different network transmission protocols; and
obtaining the resource obtaining address of the incompletely-downloaded file in the second download tool according to the resource list, and obtaining data of the incompletely-downloaded file from the resource obtaining address to complete download of the incompletely-downloaded file.

6. The method for resuming file download of claim 5 , wherein the resource identifier is a resource code, and the resource obtaining address of the same resource in the download tools performing file download by using different network transmission protocols is a download address of the same resource in the different network transmission protocols.

7. The method for resuming file download of claim 1 , wherein a format conversion comparison table is stored in a system where the first download tool and the second download tool lie and used to achieve conversion between file formats of incompletely-downloaded files stored by different download tools; and
converting the file incompletely downloaded by the first download tool to the file identifiable by the second download tool comprises: converting a file format of the file incompletely downloaded by the first download tool to a file format of the file identifiable by the second download tool according to the format conversion comparison table.

8. The method for resuming file download of claim 1 , wherein the mapping table further comprises unique identifiers and local storage addresses of the completely-downloaded and/or incompletely-downloaded files.

9. The method for resuming file download of claim 8 , wherein the unique identifier comprises at least one of file feature, file copyright information, resource name and resource download address.

10. The method for resuming file download of claim 1 , wherein
content data and download state of the incompletely-downloaded file are stored in a system where the first download tool and the second download tool lie; and
the first download tool and the second download tool only identifies the incompletely-downloaded files stored by themselves.

11. The method for resuming file download of claim 10 , wherein the download state comprises a downloaded percentage of the incompletely-downloaded file, and/or a storage address of the incompletely-downloaded file.

12. A device for resuming file download, comprising: a memory and processor configured to perform the method for resuming file download of claim 1 .

13. A non-transitory computer-readable recording medium for recording thereon a program for executing the method for resuming file download of claim 1 .
