Files.deleteDirectoryContents介绍

[英]Deletes all the files within a directory. Does not delete the directory itself.

If the file argument is a symbolic link or there is a symbolic link in the path leading to the directory, this method will do nothing. Symbolic links within the directory are not followed.
[中]删除目录中的所有文件。不删除目录本身。
如果file参数是一个符号链接，或者指向目录的路径中有一个符号链接，则此方法将不起任何作用。不遵循目录中的符号链接。
