Answer

  • Maximum file path length (includes volume name):
    • CIFS protocol: 32,767 characters.
    • NFS protocol: 4,096 characters.
  • Maximum file name length:255 characters for both CIFS and NFS.

Additional Information

  • The maximum path length includes the volume name, directory structure, and file name.
  • File name length is limited to 255 characters, regardless of the protocol.
  • Ensure that NFS clients and CIFS clients support the required path and file name lengths.
  • For CIFS, the limit aligns with Windows long file name support.
