Add any file upload field to WooCommerce single products

Question

I am using this code to upload image to my single product woocommerce page. Now I want to upload any file like psd or cdr to be uploaded as well. Can you suggest me what changes I have to made to this code.

    // Display additional product fields (+ jQuery code)
add_action( 'woocommerce_before_add_to_cart_button', 'display_additional_product_fields', 9 );
function display_additional_product_fields(){
    ?>
    <p class="form-row validate-required" id="image" >
        <label for="file_field"><?php echo __("Upload Image") . ': '; ?>
            <input type='file' name='image' accept='image/*'>
        </label>
    </p>
    <?php
}
