Files.walk 跳过目录 [英] Files.walk skip directories

问题描述

我正在尝试编写一个程序，在我的外部高清中递归地列出列表文件，但有一个我无权访问的回收站文件夹.我想跳过该文件夹，但似乎无法跳过.

I am trying to write a program the list files recursively in my external hd but there is this recycle bin folder that I don't have access to. I want to skip the folder but can't seem to do it.

下面这段代码有什么问题吗?

Is there anything wrong with this code below?

public static void main(String[] args) throws Exception
{
    String path = "K:\\";

    Files.walk(Paths.get(path))
            .filter(it -> !it.toString().startsWith("K:\\$RECYCLE.BIN"))
            .filter(Files::isRegularFile)
            .forEach(System.out::println);
}

它一直给我这个错误:

Exception in thread "main" java.io.UncheckedIOException java.nio.file.AccessDeniedException: K:\$RECYCLE.BIN\S-1-5-21-684815243-3314879918-332412784-1001
    at java.nio.file.FileTreeIterator.fetchNextIfNeeded(FileTreeIterator.java:88)
    at java.nio.file.FileTreeIterator.hasNext(FileTreeIterator.java:104)
    ...
