As long as you don't mind risking to lose the source file before you know for sure it's been successfully downloaded you can pass an input stream like this rather than the file itself:

public class DeleteOnCloseFileInputStream extends FileInputStream {

    private File _file;

    public DeleteOnCloseFileInputStream( File file ) throws FileNotFoundException {
        super( file );
        _file = file;
    }

    public File getFile() {
        return _file;
    }

    public void dismiss() throws IOException {
        _file = null;
        super.close();
    }

    @Override
    public void close() throws IOException {
        try {
            super.close();
        } finally {
            _file.delete();
            _file = null;
        }
    } }

Regards.
