  • Method, apparatus and system for accessing remote files
    Patent number: 8874625
    Abstract: The present invention relates to a method, apparatus and system for accessing remote files, wherein the method for accessing remote files comprising the following steps: obtaining download operation information for downloading a file in an operational system server; redirecting the download operation to a file server with safety space; saving a real copy of the downloaded file in the safety space and enumerating a corresponding virtual copy in the safety space. In the present invention, local file operations are redirected to the network file operations of network file storage system by redirecting the download operation on the file in the operational system server to the file server instead of being saved in the local user terminal to realize the “Not to local” effect for the key file. Even when it is power-off and then restarted, the data will not be saved in the local user terminal to achieve an effect close to “physical-like isolation”, which solves the safety problems of the offline key file much better.
