XenForo emoji.php and Ruleset.php problem

Hi!
My website URL is: https://vn-zoom.cf

What I’m seeing is: src/XF/Data/Emoji.php and src/vendor/joypixels/emoji-toolkit/lib/php/src/Ruleset.php Missing

I’m using this software: XenForo Forum Software, and WinSCP for ftp also tried FileZilla

Additional information: When I am uploading the Emoji.php and Ruleset.php file it keeps deleting
