I can't delete a file in Java (Windows 7)

I have some trouble deleting a file in Windows 7, using this code :

    private static final String WIN_DIR_TEST = "D:"+File.separator+"Users"+File.separator+"u119255"+File.separator+"Desktop"+File.separator; 
    ...
    File file = null;
    FileWriter fileWriter = null;
    String localPath = WIN_DIR_TEST.concat("abc.degno");
    file = new File(localPath);
    fileWriter = new FileWriter(file, true);
    fileWriter.write("qwertyuiop\n");
    fileWriter.close();
    ftp.send(localPath, distantPath);
    file.delete();

And this last line always return false, and I don't understand why. Also, no exception occurs.

I had issues deleted with deleting a folder containing other files.

So I ended up with deleting recursively the folder.

    private void deletedFile(File file)
{
    if ( file.isFile() )
    {
        file.delete();
    }
    else
    {
        File[] subFiles = file.listFiles();

        for ( File subFile : subFiles )
        {
            deletedFile(subFile);
        }
        file.delete();
    }
}

Try using file.deleteOnExit() instead of file.delete()

If that works maybe there's something in your code that still has a handle on the file.

Java has often Problems to write to Files which lies directly in C: Hard Disk (or the Disk where Win is installed). Move the File to a subfolder on C:.

Try to put the exception handling like this:

try {
    if (file.delete()) {
        System.out.println(file.getName() + " is deleted!");
    } else {
        System.out.println("Delete operation is failed.");
    }
} catch (Exception e) {
    e.printStackTrace();
}

It is simple, because as I can see from your code the "file" is always equals null :) Where do you initialize you file variable?
