Abstract

The invention provides a system and method for file synchronization. One embodiment of the system of this invention includes a software program stored on a computer readable medium. The software program can be executed by a computer processor to receive a file from a server; store the file as a cached file in a cache; determine if the cached file has been modified; and if the cached file has been modified, communicate the cached file directly to the database.

First claim

What is claimed is:

1. A computer system comprising:
a client computer processor;
a client computer network connection device coupled to the processor and operable to connect to a network;
a client computer memory coupled to the client computer processor the client memory having operating system space and user space;
a client computer operating system having an operating system file management system;
a user space cache manager in the client computer memory, the user space cache manager executable by the processor to perform operations comprising:
communicating with a server over the network to download a copy of a file from a file repository;
storing the downloaded copy of the file as a cached file in a local cache at the client computer, wherein the local cache comprises a location in a file system of the file management system;
interfacing with the file management system of the client computer operating system to cause an automatic notification feature to provide the cache manager automatic notifications with respect to the local cache;
in response to receiving an automatic notification with respect to the cache, determining if the cached the has been modified by another application; and
when it has been determined that the cached file has been modified, sending changes to the cached file to the server to synchronize the file at the file repository with the cached file.

2. The computer system of claim 1 , wherein the operations comprise the user space cache manager establishing the local cache without creating a new file system.

3. The computer system of claim 2 , wherein the local cache is located in a c:/ volume.

4. The computer system of claim 1 , wherein the operations further comprise the user space cache manager:
storing credentials associated for a first user; and
establishing a connection with the server using the credentials.

5. The computer system of claim 4 , wherein the user space cache manager is executable to provide bi-directional synchronization for the file in the file repository.

6. The computer system of claim 5 , wherein the operations further comprise the user space cache manager:
receiving a notification from the server that a second user has modified the file in the file repository; and
providing a notice in a graphical user interface to the first user that the second user has modified the file.

7. The computer system of claim 6 , wherein the operations further comprise the user space cache manager:
providing in the graphical user interface an option to download a copy of a latest version of the file in the file repository containing modifications by the second user; and
based on receiving an indication to download a copy of the latest version of the file in the file repository, download the copy of the latest version of the file in the file repository.

8. The computer system of claim 4 , wherein the operations further comprise the user space cache manager:
providing a client computer graphical user interface displaying items managed by the server for selection;
receiving an indication of a selected item via the graphical user interface;
communicating with the server over the network to download a copy of the selected item; and
storing the downloaded copy of the selected item in a local cache at the client computer, wherein storing the copy of the selected item in the local cache comprises the storing the copy of the file as the cached file.

9. The computer system of claim 4 , further comprising instructions executable by the client computer processor to prompt the operating system to open the cached file using an application associated with a file type of the cached file.

10. The computer system of claim 4 , wherein the operations further comprise the user space cache manager:
associating the cached file with the connection;
determining that the connection has become disconnected; and
based on the determination that the connection has become disconnected, reestablishing the connection.

11. The computer system of claim 1 , wherein the operations further comprise:
communicating with the server over the network to download a copy of a second file from the file repository;
storing the copy of a second file received over the network from the server as a second cached file in the local cache;
in response to receiving a second automatic notification with respect to the local cache, determining if the second cached file has been modified; and
based on a determination that the second cached file has been modified communicating changes to the second cached file to the server to synchronize the second file in the file repository with the second cached file.

12. The computer system of claim 1 , wherein the received automatic notification with respect to the cache comprises an automatic notification that the cached file has been saved in the local cache.

13. The computer system of claim 1 , wherein the user space cache manager is executable to synchronize changes in files in the local cache to the server regardless of file type.

14. A computer program product comprising a non-transitory computer readable medium storing instructions, the stored instructions executable by a processor of a client computer having a client computer operating system with a file management system, the stored instructions executable by the processor to provide a cache manager that resides in user space of a client computer memory having user space and operating system space, wherein the cache manager residing in user space is configured to:
communicate with a server over a network to download a copy of a file from a file repository to the client computer;
store the downloaded copy of the file as a cached file in a local cache at the client computer, wherein the local cache comprises a location in a file system of the file management system;
interface with the file management system of the client computer operating system to configure an automatic notification feature of the file management system to provide to provide the cache manager automatic notifications with respect to the local cache;
in response to receiving an automatic notification with respect to the local cache, determine if the cached file has been modified in the local cache by another application; and
based on a determination that the cached file has been modified in the local cache by another application, send changes to the cached file to the server to synchronize the file at the file repository with the cached file.

15. The computer program product of claim 14 , wherein the cache manager residing in user space is further configured to establish the local cache without creating a new file system.

16. The computer program product of claim 15 , wherein the cache manger residing in user space is further configured to establish the local cache in a c:/ volume.

17. The computer program product of claim 14 , wherein the cache manager residing in user space is further configured to:
store credentials associated for a first user; and
establish a connection with the server using the credentials.

18. The computer program product of claim 17 , wherein the cache manager residing in user space is further configured to provide bi-directional synchronization for the file in the file repository.

19. The computer program product of claim 17 , wherein the cache manager residing in user space is further configured to:
provide a client computer graphical user interface displaying items managed by the server for selection;
receive an indication of a
