Welcome to the board.

We are using in our version the GetFileTime function to get
the date of last modification of a file.
The change all "*.LOG" files to the format "YYYYMMDD.LOG". No renaming
when file is in use or new file already exist.

Our version:

code:

---

$log_directory="j:\drs1\drs1backup"
;
$tmp_file="%temp%\zzzzz.tmp"
SHELL '%comspec% /c dir "$log_directory\*.log" /b >$tmp_file '
IF (Open(1,$tmp_file,2) = 0)
   $old_file=ReadLine(1)
   WHILE (@error = 0)
      ? $old_file+" -> "+GetFileTime($old_file)
      $fdate=GetFileTime($old_file)
      IF (len($fdate) <> 0)
         $new_file=              substr($fdate,1,4)+substr($fdate,6,2)+substr($fdate,9,2)
      ;  $new_file=$new_file+"_"+substr($fdate,12,2)+substr($fdate,15,2)+substr($fdate,18,2)
         $new_file=$new_file+".log"
         ;
         IF ($old_file <> $new_file) AND (Exist($log_directory+"\"+$new_file) = 0)
            ? 'rename "$log_directory\$old_file" "$new_file" '
            shell '%comspec% /c ren "$log_directory\$old_file" "$new_file" '
         ELSE
            ? '-skip- "$log_directory\$old_file" (duplicate entry)'
         ENDIF
      ELSE
         ? '-skip- "$log_directory\$old_file" '
      ENDIF
      $old_file=ReadLine(1)
   LOOP
   IF Close(1)
   ENDIF
ENDIF
DEL $tmp_file
