6. A system comprising: a local computing device for use by a local user; a shared cloud service for storing and synchronizing statistics files and keyword files for use by a remote user; a user client export module at the local computing device for: creating a keyword file from selection criteria for suggestion of relevant documents to the local user, the selection criteria including a set of keywords; and synchronizing the keyword file with the shared cloud service as a first serialized data file; a user client import module at the local computing device in communication with the shared cloud service for retrieving a second serialized data file from the shared cloud service when the second serialized data file is synchronized to the shared cloud service by a remote device, wherein retrieving comprises: identifying the 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 the remote device; initiating, 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; receiving 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 keyword 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 keyword file from the keyword 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; and a suggestion module at the local computing device, in communication with the shared cloud service, for: identifying, using the selection criteria at the local computing device and the plurality of file statistics in the statistics file, 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 suggesting files based on the selection criteria and the statistics from the statistics file, the files including at least the identified remote content file.

The system of claim 6 , wherein the globally-unique identifier embedded in the filename of the second serialized data file identifies the associated user or file of the data file in the filename, so that information about a user or a file can be located in a particular location on the shared cloud service using the filename.
