Thanks for your advice.
I will record and gradually implement the advice you mentioned, but not now, because I am preparing for an exam that is important to me recently, maybe you will wait for a few months, I am sorry.
Regarding the software installation directory, I am sorry that I can't change it because I use the Microsoft ClickOnce technology to publish the application. The installation directory of the software can only be what you see now.
