A system for preventing duplication of a computer source file to a destination file includes a user application accessed by a user of a computer. An agent application hosted by the computer registers for a notification of a user interface action with an operating system (OS) of the computer. The agent receives notice from the OS of the user interface action and determines if the user interface action is indicative of a data file duplication operation of a source file to a destination file location The Agent compares a property of the source file and a property of the destination file location to a blocking criteria, and blocks the user interface action from reaching the application.

System and method for light data file duplication prevention

A computer-based method includes: receiving an indication from a computer's operating system that a user has performed a first action that may have caused a context menu with a paste option to open on a screen of the computer, and subsequently receiving an indication from the computer's operating system that the user has performed a second action at the computer that may have amounted to a selection of the paste option on the context menu. In response to the indication from the computer's operating system that the user has performed the second action, the method includes determining if the second action by the user amounted to a selection of the paste option on the context menu and thereby cause a paste action to occur.
