回复 1# 屡败屡战




   请问你后面改好的代码是这样 的吗？
@echo on
setlocal enabledelayedexpansion
for %%a in (*.txt) do set "txt=%%a" & call :aa&&ren "%%~fa" "!b::=!%%~xa"
pause
:aa
for /f "usebackq delims=*" %%b in ("!txt!") do (
    set "a=%%a" & set "b=%%b"
)
echo +++ "!a!" "!b!.txt"
if exist "!b!.txt" (
    echo --- 重复
) else (

)
goto :eof



为什么我改了用不了  是哪里出错了
