Abstract

A machine-implemented file sharing method for a network storage system is provided. The network storage system at least includes a first storage device, a second storage device and a network cloud. The first storage device and second storage device are in communication with the network cloud. The machine-implemented file sharing method includes the following steps. Firstly, a state of a target file of the second storage device to be retrieved by a user of the first storage device is marked as a freeze state. If it is determined the user of the second storage device is to modify the target file, a file access expediting operation on the target file is performed and a file access notice signal is issued to the user of the first storage device to expedite the retrieval of the target file.

12. The machine-implemented file sharing method according to claim 11, wherein said step (d) is performed by immediately retrieving said copy of said target file from said third storage device to said first storage device.

13. The machine-implemented file sharing method according to claim 11, wherein said step (d) is performed by marking said copy of said target file in said third storage device as said freeze state and retrieving said target file to said first storage device at a later time.

14. The machine-implemented file sharing method according to claim 4, wherein said network cloud is a private network cloud server, wherein said step (c) is performed by duplicating a copy of said target file from said second storage device to said private network cloud server, deleting said target file in said second storage device, and alerting said first storage device that a retrieving link of said copy of said target file to said private network cloud server is provided via a communication channel.

15. The machine-implemented file sharing method according to claim 14, wherein said step (d) is performed by immediately retrieving said copy of said target file from said private network cloud server to said first storage device.
