Embodiment of the invention provide a reverse name lookup function for providing an absolute path name or file name and absolute path name to the file name parent directory based on a vnode reference, NFS file handle reference, or file identifier reference associated with a computer virtual file system. A method in accordance with the invention comprises populating a table structure with vnodes, names, and absolute path information associated with the vnodes. The table structure and information are sufficient to generate an absolute path name and file name for each vnode. The table structure also includes entries for file identifiers, names, and associated absolute path information associated with the file identifiers. This information is sufficient to generate an absolute path name for each file identifier. The table is populated by hooking virtual file system function calls including the vnode name lookup function and the vnode inactive function. The table is populated with the file identifier entries by hooking the vnode inactive function.
