7z 压缩解压工具使用--命令行

压缩：“a” 属于7z的压缩命令 ; "-r" 属于7z的参数表示递归

7z a CompressFileName Source
7z a CompressFileName Source -r

解压：“x” 属于7z的解压命令 ; “-o”(字母o)属于7z的参数表示输出目录(Output) 后面紧跟目录路径, 绝对路径或相对路径 ( 以当前目录为起点 )
7z x CompressFileName
7z x CompressFileName -o
注：虽然"e"也是7z的解压命令，但与“x”不同，它好像是把所有文件全部解压到当前目录或指定目录中去，具体规则不清楚，解压后的文件很混乱。强烈建议使用x命令

分卷压缩:跟压缩所使用的命令或参数基本一致，只不过多了一个"-v"参数，其后紧跟每卷的大小，单位可以是b,k,m,g

其他的请参考下列7z的帮助内容：
