How do I write a software program to prevent folders from being copied?

I don't know what the landlord means, does it mean that the file cannot be copied in the system, or is it checked if it is copied elsewhere after being copied?
If it is the first, then this should not be easy. Even if it is realized, it can only deal with novices (people who have not yet distinguished carriage returns and spaces). Because this problem can be transposed, if you encounter such a file, what would you think of to copy it? There are too many ways, the easiest way is to enter DOS mode copy.
If it is the second kind, then it is even more difficult. How does a program know if it is a fake? Unless it is installed by another program, you can count and check the hardware. But if it is an installer itself, what does it check? The solution is not without, but no one is impeccable.

quite difficult
If you open it to exclusive mode, you can
But the problem is that your program must be running
It’s hard to protect when it’s over
pubwin is to use dll to inject expoler to prevent files from being deleted and modified
But how do you prevent it under dos?

The premise is that you are logged in as the system administrator and set a password, and others log in as ordinary users

It is better to use the domain management model for internal use of the company, for a better grasp
