This Internet based file system allows various wired and wireless computation devices such as personal computers, laptop computers, tablet computers, cell phones, and any other Internet connected devices to manage their files in their native method, however, the invention inserts itself into the operating system and creates a caching and encrypting system that maintains the files on an Internet server.All registered devices share the same files, supplanting the need for file and data synchronization, and backing up files. Many users may belong to this service, a user of the system may“share” any or all of their files (data) with any other user of the system, allowing instant access to that user, which supplants the need for email attachments, large file-sending websites or the sending physical media.Invention also includes the ability to stop data to devices when they're lost or stolen, data inheritance, restoring lost data and moving data from the Internet server onto physical storage mediums.

A method and associated system for efficiently firing mapping and transform rules during a bidirectional synchronization of two or more systems. A processor loads a set of mapping and transform synchronization rules and a set of cross-reference tables. When an event message received from a source system identifies a revision to an element of the source system's data, the processor parses the message to identify the revised source-system data. The processor uses the cross-references to identify synchronization rules that are associated with the revised data element. If any of the identified rules requires an additional source-system data element or an extrinsic data element located at an external source, the processor retrieves those further identified data elements. The processor then looks up the synchronization procedure of the identified rules, packages it into a synchronization message, and sends the message to the target system.
