推荐答案

好，如果我正确理解，您必须:

1.列出SD卡文件夹中的可用文件
2.允许用户选择文件
3.允许他指定一个文件夹(这些选定的文件必须复制到的文件夹)
4.将它们复制到该文件夹​​中

Ok, if I understood correctly you have to :

1. List up the available files in a folder of SD card
2. Allow the user to pick files
3. Allow him to specify a folder (to where these selected files have to be copied)
4. Copy them into that folder
