Abstract

A method for processing a file stored in cloud storage includes the following step: an original file is added to a sharing folder, which belongs to the owner account for sharing to at least one sharing account, on a cloud storage machine through an owner client device, which is logged in an owner account. The original file stored in the sharing folder is synchronized to at least one sharing client device, which is logged in the at least one sharing account. At least one changed file, which is amended utilizing the original file, is received from the at least one sharing client device. Difference between the at least one changed file and the original file is generated to be taken as at least one changed content. A summary about the at least one changed content is generated for being displayed on the owner client device.

Claims

1. A method for processing a file stored in cloud storage comprising:

(a) adding an original file to a sharing folder on a cloud storage machine through an owner client device, which is logged in an owner account, wherein the sharing folder belongs to the owner account for sharing to at least one sharing account;

(b) synchronizing the original file stored in the sharing folder to at least one sharing client device, which is logged in the at least one sharing account;

(c) receiving at least one changed file, which is amended utilizing the original file, from the at least one sharing client device;

(d) comparing the at least one changed file with the original file to generate at least one difference between the at least one changed file and the original file to be taken as at least one changed content;

(e) generating a summary about the at least one changed content; and

(f) displaying the summary on the owner client device.

2. The method of claim 1 further comprising:

when an accept-change signal for accepting the at least one changed content is received from the owner client device, accepting the at least one changed content to the original file stored in the sharing folder.

3. The method of claim 2 wherein when the number of the at least one changed file is more than one, the step (d) comprises:

respectively comparing the changed files with the original file to respectively generate differences between the changed files and the original file to be taken as the changed contents;

determining if there is any conflict between the changed contents;

when there is at least one conflict between the changed contents, providing a selection list for selecting one of the conflicted changed contents; and

when a selection signal is received through the selection list to select one of the conflicted changed contents, deleting the conflicted changed contents other than the selected one from the summary.

4. The method of claim 1 further comprising:

when a reject-change signal to reject the at least one changed contents is received from the owner client device, deleting the at least one changed content from the summary.

5. A system for processing a file stored in cloud storage comprising:

a network card for building a connection with a network;

a storage unit; and

a processing unit electrically connected with the network card and the storage unit, wherein the processing unit comprising;

a cloud-storage providing module for providing the storage unit as a cloud storage space through the network;

a file adding module for receiving an original file from an owner client device, which is logged in an owner account, and adding the original file to a sharing folder on the cloud storage space, wherein the sharing folder belongs to the owner account for sharing to at least one sharing account;

a synchronizing module for synchronizing the original file stored in the sharing folder to at least one sharing client device, which is logged in the at least one sharing account;

a changed-file receiving module for receiving at least one changed file, which is amended utilizing the original file, from the at least one sharing client device;

a comparing module for comparing the at least one changed file with the original file to generate at least one difference between the at least one changed file and the original file to be taken as at least one changed content, and generating a summary about the at least one changed content; and

a summary transmitting module for transmitting the summary to the owner client device, such that the owner client device displays the summary.

6. The system of claim 5, wherein the processing unit further comprises:

a change processing module for accepting the at least one changed content to the original file stored in the sharing folder when an accept-change signal for accepting the at least one changed content is received from the owner client device.

7. The system of claim 6, wherein:

when the number of the at least one changed file is more than one, the comparing module respectively compares the changed files with the original file to respectively generate differences between the changed files and the original file to be taken as the changed contents, wherein the comparing module comprises;

a conflict determiner for determining if there is any conflict between the changed contents; and

a selection list provider for providing a selection list for selecting one of the conflicted changed contents when there is at least one conflict between the changed contents;

when a selection signal is received through the selection list to select one of the conflicted changed contents, the change processing module deletes the conflicted changed contents other than the selected one from the summary.

8. The system of claim 5, wherein the processing unit further comprises:

a change processing module for deleting the at least one changed content from the summary when a reject-change signal to reject the at least one changed contents from the owner client device.

9. A non-transitory computer readable storage medium with a computer program to execute a method for processing a file stored in cloud storage, wherein the method comprises:

(a) adding an original file to a sharing folder on a cloud storage machine through an owner client device, which is logged in an owner account, wherein the sharing folder belongs to the owner account for sharing to at least one sharing account;

(b) synchronizing the original file stored in the sharing folder to at least one sharing client device, which is logged in the at least one sharing account;

(c) receiving at least one changed file, which is amended utilizing the original file, from the at least one sharing client device;

(d) comparing the at least one changed file with the original file to generate at least one difference between the at least one changed file and the original file to be taken as at least one changed content;

(e) generating a summary about the at least one changed content; and

(f) displaying the summary on the owner client device.
