I assume your app already has a way to get access to the path to the directory you want to clear, and a permission to access the storage.我假设您的应用程序已经可以访问您要清除的目录的路径，以及访问存储的权限。 Now having the path to the directory you could simply File(pathToDirectory).list().forEach{ it.delete() } Customize the behavior based on your needs.现在有了目录的路径，您可以简单地File(pathToDirectory).list().forEach{ it.delete() }根据您的需要自定义行为。 For example, you could recursively call the function containing the code above to clear a directory and all included subdirectories, or you could leave folders untouched and just delete files.例如，您可以递归调用包含上述代码的函数来清除目录和所有包含的子目录，或者您可以保持文件夹不变，只删除文件。 For that, there are fields isFile and isDirectory为此，有字段isFile和isDirectory
