1. 簡述

    遞迴解壓資料夾中的所有壓縮包到指定資料夾

2. 環境配置

    python解壓rar檔案需要安裝依賴庫 （python-unrar）

    Windows：

1. 在 RARLab 官方下載安裝庫檔案 http://www.rarlab.com/rar/UnRARDLL.exe
2. 預設路徑偽 C:\Program Files (x86)\UnrarDLL\
3. 新增環境變數 UNRAR_LIB_PATH 鍵值 C:\Program Files (x86)\UnrarDLL\x64\UnRAR64.dll，如果是32位就是 C:\Program Files (x86)\UnrarDLL\UnRAR.dll

    Linux：

1. 下載庫檔案 https://www.rarlab.com/rar/unrarsrc-5.6.8.tar.gz

2. $ make lib
   $ make install-lib

3. 新增環境變數  export UNRAR_LIB_PATH=/usr/lib/libunrar.so

3. 實現

    程式碼實現

  1 #!/usr/bin/env python3
  2 # .zip .rar .tar .tgz .tar.gz .tar.bz2 .tar.bz .tar.tgz
