我正在尝试将文件从文件夹 A：“/files/attachments/2000/filename.txt”移动到文件夹 B：“/files/attachments/trashbin/2000/filename.txt”，但我不断收到异常：FileAlreadyExistsException异常输出是：“/files/attachments/trashbin/2000”。

这是代码：

Path filePath = Paths.get(pathOnNFS.concat(folderPath).concat(Utils.DELIMITER + fileName));
Path trashBinPath = Paths.get(trashBinNFS.concat(folderPath));
try {
    Files.createDirectories(trashBinPath);
    Files.move(filePath, trashBinPath.resolve(fileName), StandardCopyOption.REPLACE_EXISTING);
}catch(...){}

任何人都可以提出为什么会这样吗？这是文档：https ://docs.oracle.com/en/java/javase/12/docs/api/java.base/java/nio/file/Files.html#move(java.nio.file.Path ,java.nio.file.Path,java.nio.file.CopyOption...)
