CF7 issue

[MakarkinPRO]

Does it's working with Contact Form 7? Looks like everytime I fill the form the ConactForm7 delete all file into my server after sending by email. How to solve it?

I found solution of commenting
//$this->remove_uploaded_files();
at submission.php file

//wpcf7_rmdir_p( path_join( $dir, $file ) );
at file.php

but after next Contact Form 7 update I need to comment it again? how to solve it?

ps: I'm sending not base64, I'm sending 'url'.
