How to remove file exists method in Magento2

In this tutorial, We’ll learn how to remove file_exists in Magento 2. Magento does not support direct use of file_exists in file. This practice is not supportable by coding standard and this can be cause of security issues. So when you check phpcs issues then you will see “file_exists is discouraged”.

You must use an alternative method of file_exists when using Magento 2 to avoid this problem.


 * @var \Magento\DownloadableImportExport\Helper\Uploader
protected $uploaderHelper;

 * @param \Magento\DownloadableImportExport\Helper\Uploader $uploaderHelper
public function __construct(
    \Magento\DownloadableImportExport\Helper\Uploader $uploaderHelper
) {
   $this->uploaderHelper = $uploaderHelper;

public function isFile($fileName)
  if ($this->uploaderHelper->isFileExist($fileName)) {
     //write your code
