Systems and methods for determining and facilitating content updates for a user device

1. A method of updating content, comprising:

determining, using a server, a first version of content residing on a user device, the first version of the content being associated with a first archive having a first set of files organized within the first archive in a first sequential order based on when each file in the first set of files was last modified, each file within the first set of files being associated with the first version;

determining, using the server, a second version of the content, the second version of the content being associated with a second archive having a second set of files organized within the second archive in a second sequential order based on when each file in the second set of files was last modified, the second set of files having at least one subject file associated with the second version in a sequential order with respect to other files in the second set of files that is different from a sequential order of a corresponding file associated with the first version with respect to other files in the first set of files;

using the server, sequentially accessing, based on the second order of the second set of files in the second archive, version information of each file within the second set of files, the version information indicating a version of each file;

determining from the version information of the files of the second set of files that at least the subject file is associated with a newer version of the content than that which resides on the user device; and

allowing the user device to retrieve the subject file of the second set of files and additional files of the second set of files being ordered within the second archive sequentially after the subject file.

2. The method of claim 1 , further comprising:

comparing the first set of files in the first archive to the second set of files in the second archive;

determining one or more files being included in the first set of files and excluded from the second set of files; and

instructing the user device to delete the one or more files from the user device.

3. The method of claim 1 , wherein the second archive maintains metadata associated with the second order of the second set of files, the version information of each file within the second set of files being included in the metadata.

4. The method of claim 1 , wherein the subject file is associated with an addition of new content to the first version of the content residing on the user device.

5. The method of claim 1 , wherein the subject file is associated with a modification of at least a portion of the first version of the content residing on the user device.

6. The method of claim 1 , wherein the subject file is associated with a deletion of at least a portion of the first version of the content residing on the user device.

7. The method of claim 1 , further comprising:

receiving a revision to the first version of the content; and

creating the second archive in response to receiving the revision.

8. The method of claim 7 , further comprising:

sending a notification to the user device indicating the revision to the first version of the content.

9. The method of claim 1 , wherein the method is performed in response to receiving a request to update the first version of the content residing on the user device.

10. The method of claim 1 , wherein the method is automatically performed when new content becomes available.

11. A system, comprising:

an archive storage medium configured to store archives of files; and

a delivery module configured to:

determine a first version of content residing on a user device, the first version of the content being associated with a first archive in the archive storage medium having a first set of files organized within the first archive in a first sequential order based on when each file in the first set of files was last modified, each file within the first set of files being associated with the first version,

determine a second version of the content, the second version of the content being associated with a second archive in the archive storage medium having a second set of files organized within the second archive in a second sequential order based on when each file in the second set of files was last modified, the second set of files having at least one subject file associated with the second version in a sequential order with respect to other files in the second set of files that is different from a sequential order of a corresponding file associated with the first version with respect to other files in the first set of files,

sequentially access, based on the second order of the second set of files in the second archive, version information of each file within the second set of files, the version information indicating a version of each file,

determine from the version information of the files of the second set of files that at least the subject file is associated with a newer version of the content than that which resides on the user device, and

allowing the user device to retrieve the subject file of the second set of files and additional files of the second set of files being ordered within the second archive sequentially after the subject file.

12. The system of claim 11 , wherein the delivery module is further configured to:

compare the first set of files in the first archive to the second set of files in the second archive;

determine one or more files being included in the first set of files and excluded from the second set of files; and

instruct the user device to delete the one or more files from the user device.

13. The system of claim 11 , wherein the second archive maintains metadata associated with the second order of the second set of files, the version information of each file within the second set of files being included in the metadata.

14. The system of claim 11 , wherein the subject file is associated with an addition of new content to the first version of the content residing on the user device.

15. The system of claim 11 , the subject file is associated with a modification of at least a portion of the first version of the content residing on the user device.

16. The system of claim 11 , the subject file is associated with a deletion of at least a portion of the first version of the content residing on the user device.

17. A computer-readable storage medium storing instructions which, when executed by a processor, cause the processor to perform operations comprising:

determining a first version of content residing on a user device, the first version of the content being associated with a first archive having a first set of files organized within the first archive in a first sequential order based on when each file in the first set of files was last modified, each file within the first set of files being associated with the first version;

determining a second version of the content, the second version of the content being associated with a second archive having a second set of files organized within the second archive in a second sequential order based on when each file in the second set of files was last modified, the second set of files having at least one subject file associated with the second version in a sequential order with respect to other files in the second set of files that is different from a sequential order of a corresponding file associated with the first version with respect to other files in the first set of files;

sequentially accessing, based on the second order of the second set of files in the second archive, version information of each file within the second set of files, the version information indicating a version of each file;

determining from the version information of the files of the second set of files that at least the subject file is associated with a newer version of the content than that which resides on the user device; and

allowing the user device to retrieve the subject file of the second set of files and any additional files of the second set of files being ordered within the second archive sequentially after the subject file.

18. The computer-readable storage medium of claim 17 , wherein the instructions further cause the processor to perform operations comprising:

comparing the first set of files in the first archive to the second set of files in the second archive;

determining one or more files being included in the first set of files and excluded from the second set of files; and

instructing the user device to delete the one or more files from the user device.

19. The computer-readable storage medium of claim 17 , wherein the subject file is associated with an addition of new content to the first version of the content residing on the user device.

20. The computer-readable storage medium of claim 17 , the subject file is associated with a modification of at least a portion of the first version of the content residing on the user device.
