无法通过Java删除目录 [英] not able to delete the directory through Java

问题描述

在我的应用程序中，我编写了从驱动器中删除目录的代码，但是当我检查File的删除功能时，它不会删除该文件。我写过这样的东西

In my application I have written the code to delete the directory from drive but when I inspect the delete function of File it doesn't delete the file. I have written some thing like this

//Code to delete the directory if it exists
File directory = new File("c:\\Report\\");
if(directory.exists())
directory.delete(); 

该目录尚未使用仍然无法删除目录

the directoryis not in used still it is not able to delete the directory

推荐答案

在Java中，目录删除只能用于空目录，这会产生如下方法：

in Java, directory deletion is possible only for empty directory, which leads to methods like the following :

/**
 * Force deletion of directory
 * @param path
 * @return
 */
static public boolean deleteDirectory(File path) {
    if (path.exists()) {
        File[] files = path.listFiles();
        for (int i = 0; i < files.length; i++) {
            if (files[i].isDirectory()) {
                deleteDirectory(files[i]);
            } else {
                files[i].delete();
            }
        }
    }
    return (path.delete());
}

这个会删除你的文件夹，即使非空，也没有麻烦（当此目录被OS锁定时除外。

This one will delete your folder, even if non-empty, without troubles (excepted when this directory is locked by OS).
