  • Patent number: 9110920
    Abstract: A file handle produced by a file server is encoded into a pseudo-pathname used as a substitute for a pathname in a network file access protocol for accessing a file in the file server. The method avoids repeating a directory lookup and may permit the network file access protocol to access a file that has been renamed since the file handle was produced. The method is particularly advantageous for enabling a file server to use a CIFS client for virus checking or backup of a file modified by an NFS client. In a preferred implementation, the encoding of the file handle into a pseudo-pathname involves converting the file handle to an ASCII hexadecimal format to produce a component name, and appending the component name to a special name of a pseudo-directory of file handles of files in a file system.
