Abstract

Claims (52)

1. A method for automatic synchronization of recently modified data between a plurality of devices, comprising:

identifying, by a first device, a first file stored in a folder in a first storage device, the first file having a modification time within a predetermined time period of a present time;

storing, by the first device responsive to the identification of the first file having a modification time within the predetermined time period of the present time, an identification of the folder in the first storage device in a second file in the first storage device;

transmitting, by the first device to a second device, the first file;

receiving, by the first device from the second device at a subsequent time, a further modified version of the first file;

retrieving, by the first device, the identification of the storage location of the first file in the first storage device from the second file; and

replacing, by the first device, the first file in the first storage device with the further modified version of the first file;

wherein the identification of the folder is not transmitted by the first device to the second device.

2. The method of claim 1 , wherein transmitting the first file to the second device comprises transmitting the first file for storage by the second device in a hidden directory of a second storage device.

3. The method of claim 1 , wherein identifying the first file further comprises determining to synchronize the first file responsive to an active window title bar name comprising a name of the first file.

4. The method of claim 3 , further comprising identifying, from a file system of the first device, a plurality of files including the first file having modification times within the predetermined time period of the present time, and determining to synchronize the first file of the plurality of files responsive to the active window title bar name comprising the name of the first file.

5. The method of claim 1 , further comprising:

receiving, by the first device from the second device, an identification of a modified version of a second file;

determining, responsive to a synchronization policy, not to retrieve the second file; and

displaying, by the first device to a user, an indication that the second file was modified.

6. The method of claim 5 , wherein the synchronization policy identifies a file type that should not be retrieved.

7. The method of claim 5 , wherein the synchronization policy identifies a file size threshold, such that files with sizes exceeding the threshold should not be retrieved.

8. The method of claim 5 , further comprising subsequently retrieving, by the first device responsive to a request of the user, the modified version of the second file from the second device.

9. A method for automatic synchronization of recently modified data between a plurality of devices, comprising:

receiving, by a first device maintaining a first storage device, a first file stored in a second storage device maintained by a second device, the first file having a modification time within a first predetermined time period of a present time;

storing, by the first device, the first file in a hidden directory of the first storage device maintained by the first device; and

displaying, by the first device to a user, an identification of the first file and the modification time;

wherein the first device does not receive an identification of any portion of a storage location of the first file in the second storage device.

10. The method of claim 9 , further comprising:

modifying, by the first device at a subsequent time, the first file in the hidden directory of the first storage device; and

transmitting, by the first device to the second device, the modified first file to replace the first file stored in the second storage device;

wherein the first device does not transmit the storage location of the first file in the second storage device to the second device.

11. The method of claim 9 , further comprising identifying, from a file system of the first device, a plurality of files including the first file having modification times within a second predetermined time period of the present time, and determining to synchronize the first file of the plurality of files responsive to the active window title bar name comprising the name of the first file.

12. The method of claim 9 , wherein displaying an identification of the first file and the modification time comprises displaying an identification of the first file in a list of recently modified files of the first device and second device.

13. The method of claim 9 , further comprising:

receiving, by the first device from the second device, an identification of a modified or created version of a second file;

determining, responsive to a synchronization policy, not to retrieve the second file; and

displaying, by the first device to the user, an indication that the second file was modified or created.

14. The method of claim 13 , further comprising retrieving, by the first device from the second device, the modified or created version of the second file, responsive to a request of the user.

15. A method for automatic synchronization of recently modified data between a plurality of devices, comprising:

receiving, by a first device from a second device, a first file stored in a first storage device maintained by the second device, the first file having a modification time within a first predetermined time period of a present time; and

transmitting, by the first device to a third device, the first file for storage in a hidden directory of a second storage device maintained by the third device;

wherein the first device does not receive an identification of any portion of a storage location of the first file in the first storage device;

receiving, by the first device from the third device at a subsequent time, a further modified version of the first file; and

transmitting, by the first device to the second device, the further modified version of the first file for replacement of the first file in the first storage device;

wherein the first device does not transmit the storage location of the first file in the first storage device to the second device.

16. The method of claim 15 , further comprising storing, by the first device, an indication that the first file is owned by the second device.

17. The method of claim 15 , further comprising:

receiving, by the first device from the second device, an identification of a modified version of a second file;

determining, responsive to a synchronization policy, that the second file should not be transmitted to the third device; and

transmitting, to the third device for display, an identification that the second file was modified, without transmitting the second file to the third device, responsive to the determination.

18. The method of claim 17 , wherein the synchronization policy identifies a file type that should not be transmitted to the third device.

19. The method of claim 17 , wherein the synchronization policy identifies that files with sizes exceeding a predetermined file size threshold should not be transmitted to the third device.

20. The method of claim 17 , wherein the synchronization policy identifies that files should not be transmitted to the third device if a connection between the first device and third device has a speed below a predetermined connection speed threshold.

21. The method of claim 17 , further comprising:

receiving, by the first device from the third device, a request from a user of the third device for the modified second file; and

transmitting, by the first device to the third device, the modified second file responsive to the request.
