当我在控制器中进行更改时，已更新已发布文件夹中的哪些文件？

I have a web application that I need to deploy, but the problem is the transfer rate is very slow. So when I publish the application, I am just copying the files that have changes. For example, I made a changes in Index view, I would just copy and paste it in my publish folder, instead of publishing the whole project. But when it comes with Controllers, I have no idea on what files are changed. Any help would be greatly appreciate.I have a web application that I need to deploy,
