Patent ID: 8412731

Claim:
A computer implemented file system method for managing file access, the method comprising: detecting a file move request for moving a file, wherein the file is identified by a filename and a file source location, from the file source location to a file target location, wherein the filename does not change; creating a file move link for the file associating the file source location with the file target location; storing the file move link within a file move link storage structure of the computer file system for a subsequent file access request; detecting a file access request searching for a file move link associated with the file and the file source location; retrieving the file target location associated with the file move link if a file move link is found; and providing access to the file at the file target location; and after the searching: defining a new file path for the file if a file move link is not found, the new path being defined by concatenating a parent file path of the file; and repeating the searching for the new file path.
