A method is described for insuring the use of the correct file on a computer. Many computer operating systems use qualifiers for identifying data on disk. For example, on the IBM Personal Computer (PC), a tree structure is used with a root directory and multiple subdirectories. The same file name can exist in different directories. It is often important to be sure that the file that is being accessed is the correct file and not just a file named the same existing on another directory. The best method for assuring that the correct file is accessed is to store all of the file qualifier information for reference whenever the file is retrieved. This method assures that the correctly named file on the correct subdirectory is the one obtained.
