Abstract: A method for monitoring file system requests made by an application program, storing changes made to a first copy of a selected file by the application program into a first file and synchronizing the changes made to the selected file with a second copy of the selected file. The monitoring and storing process is application independent in that it is utilized by the operating system for all file system requests made by any application program. The monitoring and storing process is repeated each time a file system request is made by the application program to track changes made to the selected file. At the time of synchronization, if the application program is no longer modifying the selected file and the selected file is closed, all entries in the first file are applied to the second copy of the selected file. As a result, synchronization of both copies of the selected files is achieved.

Abstract: An application independent method for monitoring file system requests made by any application program, storing changes made to a first copy of a selected file by the application program into a first file and synchronizing the selected file, whether the file is open or closed, with a second copy of the selected file. The monitoring and storing process is repeated each time a file system request to write into the selected file is made by the application program to track changes made to the selected file. At the time of synchronization, if the selected file is closed, all the changes that are stored in the first file are applied to a second copy of the selected file. If, however, the selected file is open, a portion of the changes are selected pursuant to a predetermined time period and applied to a second copy of the selected file. As a result, both copies of the selected files are identical, thereby synchronizing them.
