11. A networked computing system comprising: a processor; a network interface coupled to the processor for communicating with a shared cloud service; a data storage device coupled to the processor; and a memory coupled to the processor and including computer-readable instructions that, when executed by the processor, cause the processor to: determine, at a local computing device, selection criteria for suggestion of relevant documents to the local user, including a set of keywords; synchronize, to a shared cloud service, the selection criteria as a first serialized data file; identify a remote content file using a globally-unique identifier for the remote content file, wherein the globally-unique identifier is embedded in a filename of a second serialized data file, wherein: the second serialized data file is a Javascript Object Notation data format (JSON); and the second serialized data file is associated with a remote device; initiate, by identifying a globally-unique identifier for the local user, authenticated access to the second serialized data file via the shared cloud service, wherein the globally-unique identifier for the local user is used for tracking all statistics regarding file accesses associated with the local user; receive the second serialized data file at the local computing device from the shared cloud service when the second serialized data file is synchronized to the shared cloud service by the remote device, wherein: the second serialized data file reflects a single up-to-date state of the second serialized data file in the shared cloud service; the second serialized data file includes metadata relating to the remote content file, the metadata being created by the remote device when the first serialized data file was synchronized to the remote device and in response to a remote user opening a remote content file on the remote device, and the remote device determined the remote content file included one or more of the selection criteria from the first serialized data file after the remote user accessed the remote content file, the metadata including data indicative of one or more keywords from the set of keywords occurring in the remote content file and document metadata identifying the remote content file; and the second serialized data file has a filename generated as a function of the remote content file and is saved separately from the remote content file; determine at the local computing device, using the plurality of file statistics from the second serialized data file and the selection criteria that the remote content file is a relevant document, wherein the remote content file would not have been identified based on just the selection criteria determined at the local computing device; and suggest at least the remote content file to the local user in response to the determined selection criteria in a table of suggestions.
14. The networked computing system of claim 11 , the computer-readable instructions further causing the processor to store the plurality of file statistics in a data file that is in a metadata directory in a file hierarchy at the shared cloud service and synchronized with the local device.
