A method of sharing and synchronizing a plurality of electronically stored resources between a cloud file system and a client file system is provided. The method includes receiving one or more change events wherein each change event indicates an independent change to one or more electronically stored files in a first client file system, holding the received change events for a period of time, and determining whether any of the held change events are combinable with other held change events indicating one or more independent changes to one or more electronically stored files in one or more client file systems comprising the first client file system. The method further includes combining the combinable change events into an aggregate change event, and dispatching the aggregate change event for processing after it is held for a predetermined period of time, wherein the processing of the dispatched change event effects a synchronization of the one or more electronically stored files between the one or more client file systems and a cloud file system.

Sharing and synchronizing electronically stored files

A method of sharing and synchronizing a plurality of electronically stored resources between a cloud file system and a client file system is provided. The method includes identifying the plurality of electronically stored resources, which are stored in the cloud file system and have identical names in the cloud file system. The method also includes generating in the client file system a replicate of a first resource of the plurality of electronically stored resources, and generating in the client file system a replicate of a second resource of the plurality of electronically stored resources. The method further includes naming the replicate of the second resource of the plurality of electronically stored resources with an incremental counter to create a unique name for the replicate of the second resource of the plurality of electronically stored resources in the client file system.

Aspects of the present disclosure are directed to architectures, methods and systems and structures that facilitate the sharing and synchronization of electronically stored files among and between cloud entities and a number of computers, systems, devices and/or users. One particular exemplary aspect includes the mapping and/or translation of files electronically stored in a cloud file system when synchronized and/or shared with client computer systems.

Aspects of the present disclosure are directed to architectures, methods and systems and structures that facilitate the sharing and synchronization of electronically stored files among and between cloud entities and a number of computers, systems, devices and/or users. One particular exemplary architectural aspect includes the concurrent determination of file system changes within a cloud file system and a client file system, the serial ordering of necessary file system operations in response to the determined file system changes, and the concurrent execution of file system operations such that the cloud file system and the client computer file system are synchronized.

Aspects of the present disclosure are directed to architectures, methods and systems and structures that facilitate the sharing and synchronization of electronically stored files among and between cloud entities and a number of computers, systems, devices and/or users. One particular exemplary architectural aspect includes the serial processing and ordering of work items associated with file system changes such that correct parallel execution of the work items may proceed resulting in the synchronization of the cloud file system and the client computer file system.
