Windows ForFiles 删除 过期 文件

@echo off

set logFile=DELETE_DOS.log
set weekName=WEEK
set dayName=DAY

echo --------- Delete Expired Files ------------ >> %logFile%

echo Start (%date% %time%) >> %logFile%

echo 删除文件夹 %weekName%  下过期 (30days) 的文件, Please wait... >> %logFile%
forfiles /p "%weekName%" /m *.* /d -30 >> %logFile%
forfiles /p "%weekName%" /m *.* /d -30 /c "cmd /c del @path" >> %logFile%

echo 删除文件夹 %dayName% 下过期(7days)的文件, Please wait... >> %logFile%
forfiles /p "%dayName%" /m *.* /d -7 >> %logFile%
forfiles /p "%dayName%" /m *.* /d -7 /c "cmd /c del @path" >> %logFile%

echo End (%date% %time%) >> %logFile%
exit

此DOS命令将删除WEEK(超过30天)和DAY(超过7天)文件夹下过期的文件，并将删除日志写入 DELETE_DOS.log

另外，有关DOS中ECHO命令的用法，稍作整理：

@ 关闭单行回显
echo off 　　从下一行开始关闭回显
@echo off　 从本行开始关闭回显
echo on 　　从下一行开始打开回显
echo 　　　  显示当前是echo off/on状态
echo. 　　　 输入回车换行，空白行,同(echo, echo; echo+ echo[ echo] echo/)
