echo 清除系统LJ完成！
echo. & pause
拿第一条来说：
del /f /s /q %systemdrive%\*.tmp
del 是DOS下的删除命令
/f 加个参数/f表示强制删除只读文件
/s 这个表示包括所有子目录中的文件
/q 这个表示不需要删除确认
%systemdrive% 代表系统盘，通常为C:\
*.tmp 所有的临时文件，*是通配符，tmp是临时文件的扩展名。
命令执行的结果就是删除系统盘所有的临时文件。想删别的盘的文件，把%systemdrive%\改成别的盘符，如D:\等等。
._mp也是一种临时文件
.log是日志文件
.gid后缀的文件是windows的全索引文件
.CHK的文件是你在使用“磁盘碎片整理程序”整理硬盘后所产生的“丢失簇的恢复文件”
.old是某些文件发生改变后，系统自动将改动前的文件编程old文件
.bak是备份文件，通常是一些软件在打补丁的时候生成的！防止打补丁后软件不能使用
recycled文件夹就是回收站
Prefetch文件夹是Windows XP自动创建的，主要用于加快系统启动的速度。正常运行的情况下，Windows XP会自动记录下启动时运行的每一个程序，并建立一个资料索引以加快下一次启动的时间。而当运行的程序重名时，系统会自动在程序名的后面添加一个“后缀”，随着使用时间的变长，Prefetch文件夹内会堆放许多垃圾，反而会拖慢系统，所以如果你有精力的话，还是建议对其进行定期删除。
所有的temp文件夹都是临时文件夹
cookies文件夹中是上网生成的cookies文件，这个真没用~
recent文件夹里是文件的打开记录
Temporary Internet Files文件夹是所有上网时的临时文件
%windir%就是指windows系统文件的安装目录
%userprofile%是登陆帐户的个人文件夹
@echo off 的功能是隐藏作用
而echo 是显示作用
看了你的批处理资料，你有运行就会出现“正在清除系统垃圾文件，请稍等...... ”
等一下，应该出现“ 清除系统垃圾完成”
echo. & pause //暂停 任意键结束
