无法通过Java删除目录

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

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

The directory is not in use: 仍然无法删除该目录。

原文

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();

The directory is not in use: still it is not able to delete the directory.

在Java中，目录删除只能针对空目录，这会导致类似以下的方法：

/**
 * 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());
}

这个方法将删除您的文件夹，即使非空目录，也不会出现任何麻烦（除非该目录被操作系统锁定）。

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());
}

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