java FileUtils.delete() not deleting folder

Question

Whats wrong with my code ? with reference with this question

the folder is not being deleted.

    File f = new File(directory+"\\OOO");
    if (f.exists())
    {            
        System.out.println(f);

        FileUtils.delete(f);

        f.delete();
    //  f.mkdir();
    }
    else
    {
        System.out.println("created");

        //f.mkdir();
    }

How is `System.out.println("d");` related to the question ? Check if `f` is a valid folder by `f.isDirectory()` — c0der, Mar 17 '17 at 07:44
Please fistly check that which library you use. Check that you use [apache.commons.io](https://commons.apache.org/proper/commons-io/) library. — Vugar Suleymanov, Mar 17 '17 at 08:09
Your FileUtils import statement is using the wrong library. Also, you should pick an answer — Alkanshel, Dec 21 '17 at 22:06

FileUtils does not contain any method named delete();
You should use deleteDirectory() to recursively delete directory.
Or you can also use deleteQuitely() to suppress any exceptions while deletion.

you should be doing like this `FileUtils.deleteDirectory(f)` in case static import is not there. – Shubham Chaurasia Mar 17 '17 at 07:53

FileUtils does not contain any method named delete(), so you should use deleteDirectory() instead. Also, please ensure you have imported the correct Java file utility class from Apache Commons IO. If it is not the case, your need to

Download Apache Commons IO as a JAR file, link it to the classpath
Or declare a dependency the Apache Commons IO in your Maven, or other dependency management system.

Here's the code:

import org.apache.commons.io.FileUtils;

public class YourClass
{

    public void yourMethod() throws IOException
    {
        File f = new File(directory+"\\OOO");
        if (f.exists())
        {            
            FileUtils.deleteDirectory(f);
        }
        ...
    }
}

This may help

   try {
        FileUtils.deleteDirectory(new File("path");
        //path Example - C:\\myfolder\\foldertodelete
    } catch (IOException e) {

    }
