//    例:把E:\web\目录下的所有东西打包为1.rar放到E:\web\目录下,以便下载//"C:\Program Files\WinRAR\Rar.exe" a -k -r -s -m1 E:\web\1.rar E:\web\//参数说明://a 添加文件到压缩文件中//-k 锁定压缩文件//-s产生固体存档,这样可以增大压缩比//-r包括子目录//-m1 设置压缩比//   -m0   存储      添加到压缩文件时不压缩文件。//   -m1   最快      使用最快方式(低压缩)//   -m2   较快      使用快速压缩方式//   -m3   标准      使用标准(默认)压缩方式//   -m4   较好      使用较好压缩方式(较好压缩,但是慢)//   -m5   最好      使用最大压缩方式(最好的压缩,但是最慢)
