STRU (Specify File Structure)

FTP server subcommand

To specify the structure of a file as a continuous sequence of data bytes, use the STRU FTP server subcommand in this format:

STRU [F | R]

F
A file structure. The file structure is a continuous sequence of data bytes.
R

Notes:
  1. The file structure affects the transfer mode and the interpretation and storage of a file.
  2. If there is no parameter, the server returns a reply that indicates the present specification for file structure.
