1. A method comprising: parsing an operating system file to extract local file usage information of a client processing device for a first local file, wherein the local file usage information comprises local usage activity of the first local file on a local client device by a first user; determining, in view of communication between the client processing device and a remote network host via a network, remote file usage information of the client processing device for a Web application file stored on the remote network host, wherein the remote file usage information is maintained by the remote network host and comprises remote usage activity of the Web application file on the remote network host by the first user; compiling, by the client processing device, the local file usage information of the first user for the first local file and the remote file usage information of the first user for the Web application file to create a merged list of unified file usage information, wherein the merged list of unified file usage information comprises a first representation of the first local file associated with the local file usage information and a second representation of the Web application file associated with the remote file usage information; sorting the merged list of unified file usage information in view of a comparison of the local file usage information of the first user for the first local file and the remote file usage information of the first user for the Web application file; generating, by the client processing device, a display of the merged list of unified file usage information, as sorted; receiving a selection of the first local file from the merged list of unified file usage information, as sorted; in response to the selection, opening the first local file with a network application; and identifying, in view of the opening of the first local file with the network application, that a second local file can be moved to the remote network host.
