Abstract

A system and a method are disclosed for receiving a file at a cloud-based storage system and storing the file in the file structure of the cloud-based storage system. Once received, the file, the name of the file, and its storage location in the cloud storage are associated with a unique identifier created for the file. The file, when provided to at least one user client, can be stored by the user client in a user-defined file structure that is different from the cloud-based storage system file structure. Because of the unique identifier associated with the file and the cloud-based storage location, the locally stored files can still be synchronized with file stored at the cloud-storage location.

Claims

1. A method comprising:

receiving a file comprising file contents, a file name, and meta-data;

storing the file contents at a first cloud storage location the first cloud storage location added to the meta-data; and

2. The method of claim 1, further comprising:

receiving a request from a browser of the first user device to access the file contents transmitting a request to the user client to initiate downloading the file contents, the

transmitted request comprising;

instructing first user client to download the file contents stored at the cloud storage location;

using the meta-data of the file to identify the cloud storage location;

instructing the first user client to store the file contents at the first user client storage location; and

3. The method of claim 1, wherein providing the file further comprises:

providing a file placeholder to the first user client, the file placeholder comprising file meta-data used for locating the file contents;

receiving a user selection of the file placeholder, the user selection transmitting the meta-data associated with the file placeholder; and

responsive to receiving the user selection of the file placeholder and the meta-data, providing the file to the first user client.

4. The method of claim 1, further comprising:

receiving a request to access the file contents from a second user client, the request identifying the file contents using the file meta-data;

determining whether the second user client includes a second user file structure for storing the file contents;

changing the file stored at the first user client storage location according to the change received from the second copy of the file.

6. The method of claim 1, further comprising:

providing a second copy of the file to a second user client;

receiving a change to the second copy of the file; and

changing the file stored at the first user client according to the change received from the second copy of the file.

storing the file contents at the second cloud storage location at the second cloud-based storage system; and

updating the meta-data to identify the storage location of the file contents as the second cloud storage location.

9. The method of claim 1, further comprising:

receiving a changed hash of the file contents, the file contents changed by the user;

identifying the changes in the file contents by comparing the changed file contents to a reference copy of the file contents; and

changing the file contents at the cloud storage location to include the identified changes by transmitting only the changes in the file contents.

10. The method of claim 1, wherein the first user client is on the first user computing device in the same local area network in communication as a second user client is on a second user computing device;

12. The system of claim 11, further comprising:

a web browser for finding and opening the latest version of the file contents;

a user client for receiving a request from the web browser to access the latest version of the file contents; and

a sync engine for searching for a storage location of the latest version of the file contents by searching a computing device responsive to the request by the user client.

13. The system of claim 11, wherein the first user client is on the first user computing device in the same local area network in communication as a second user client is on a second user computing device;

the second user client obtains the file contents by requesting it from the first user client.

14. The system of claim 11, wherein the server is further configured for transmitting a request to the user client to initiate downloading the file contents, the transmitted request comprising:

using the meta-data of the file to identify the first cloud storage location of the file contents;

instructing first user client to download the file contents stored at the cloud storage location;

instructing the first user client to store the file contents at the first user client storage location; and

instructing the first user client to open the file contents.

15. The system of claim 11, wherein the server is further configured for providing the file, the providing further comprising:
