除以1024得到其KB单位的大小  当心溢出

@echo off&setlocal enabledelayedexpansion
for /f "delims=" %%i in ('dir /b /a-d *.txt') do (
  set str=%%~zi
  if %%~zi lss 1024 (set k=字节&set z=%%~zi)else set k=KB&call :lp
  call echo  %%~fi !z! !K!
  set z=&set n=&set l=
)
pause&exit
:lp
    set/a l=%l%%str:~,1%%%1024,s=%l%%str:~,1%/1024
    if %z%#==0# set z=
    set z=%z%%s%
    set str=%str:~1%
    if defined str goto lp
    set z=%z%.
:lp1
    set/a l*=10,s=l/1024,n+=1
    if %n% lss 3 (
    set z=%z%%s%
    set/a l=l%%1024
    goto lp1
)
