Answer 2

use Magento\MediaStorage\Model\File\UploaderFactory;

protected $uploaderFactory;


public function __construct(
    ...
    UploaderFactory $uploaderFactory    
    ....
) {
    ....
    $this->uploaderFactory = $uploaderFactory;  
    ....
}

    $uploader = $this->uploaderFactory->create(['fileId' => $fileId]);
    $uploader->setFilesDispersion(false);
    $uploader->setFilenamesCaseSensitivity(false);
    $uploader->setAllowRenameFiles(true);
    $path='YOUR DIRECTORY PATH';
    $result = $uploader->save($path);

Where $fileId is your name of input file
