minizip是依托于zlib软件包的一个zip格式解、压缩的软件包。minizip是zlib官方认可的一个第三方库。

教程：https://blog.csdn.net/whahu1989/article/details/80344373

主要接口文件

• zip.c：负责将多文件压缩为zip压缩包相关
• unzip.c：负责zip压缩包解压相关

提供命令2个

1. miniunz 解压命令

负责解压zip压缩包，命令如下：

Usage : miniunz [-e] [-x] [-v] [-l] [-o] [-p password] file.zip [file_to_extr.] [-d extractdir]

  -e  Extract without pathname (junk paths)
  -x  Extract with pathname
  -v  list files
  -l  list files
  -d  directory to extract into
  -o  overwrite files without prompting
  -p  extract crypted file using password

2. minizip 压缩命令

负责将多文件压缩为zip压缩包，命令如下：

Usage : minizip [-o] [-a] [-0 to -9] [-p password] file.zip [files_to_add]

  -o  Overwrite existing file.zip
  -a  Append to existing file.zip
  -0  Store only
  -1  Compress faster
  -9  Compress better

如何获取软件包

RT-Thread online package -> 
     miscellaneous package -> 
         [*] minizip: zip manipulation library --->

注意

如果只是列出zip压缩包的文件，该操作不会占用多少内存。但是如果要进行解、压缩操作，需要占用很大的内存，至少300KB左右，建议使用配备外置SRAM的开发板进行尝试。
