        } catch (Throwable $e) {

            $fileExist = false;

        }

 

        if (empty($fileName) || !$fileExist) {

            $this->messageManager->addErrorMessage(__('Please provide valid export file name'));

 

            return $resultRedirect;

        }

 

        try {

           

            $path = 'export/' . $fileName;

            $directory = $this->filesystem->getDirectoryRead(DirectoryList::VAR_IMPORT_EXPORT);

            if ($directory->isFile($path)) {

                return $this->fileFactory->create(

                    $fileName,

                    $directory->readFile($path),

                    DirectoryList::VAR_DIR,
