NAME

       Data - Contains data to be sent to remote systems

SYNOPSIS

       /usr/spool/uucp/LocalSystemName/D.SystemNamexxxx###

DESCRIPTION

       Data  (D.*)  files  contain the data to be sent to remote systems by the uucp uucico daemon.  The full pathname of a data file is a form of
       the following: /usr/spool/uucp/SystemName/D.SystemNamexxxx###

       where the SystemName directory and the SystemName portion of the file name indicate the name of the remote system.  The xxxx### notation is
       the hexadecimal sequence number of the Command (C.*) file associated with that data file; for example, D.venus471afd8.

       After  a  set  period  of  time	(specified by the uusched daemon), the uucico daemon transfers the data file to the designated system.	It
       places the original data file in a subdirectory of the uucp spooling  directory	named  /usr/spool/uucp/SystemName,  where  the	SystemName
       directory is named for the computer that is transmitting the file, and creates a Temporary (TM.*) file to hold the original data file.

       After  receiving the entire file, the uucp program takes one of three actions: If the file was sent with the uucp command and there were no
       transfer problems, the program immediately renames the TM.*  file with the appropriate data filename, such as D.venus471afd8, and sends	it
       to  the specified destination.  If the file was sent with the uuto command, the uucp  program also renames the temporary data file with the
       appropriate D.*	filename.  It then places the data file in the public directory /usr/spool/uucppublic, where the user  receives  the  data
       file  and  handles  it  with  one of the uupick command options.  If there were transfer problems (such as a failed login or an unavailable
       device), the temporary data file remains in the spooling subdirectory.  The uudemon.cleanu command, a shell  script,  removes  these  files
       automatically at specified intervals, or they can be removed manually.
