How to check if there is a new file in a folder?

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

Dear NG,

I want to check if there is a new file in a specific folder. If I copy
a big file into the folder (while the programm is running), I already
can access it. There is the problem: how can I check if a file is
already copied or not!? How do I know if a file is "ready" for use?

I open the CheckMyFolder function once a second:

public void CheckMyFolder()
....
files = directory.GetFiles();

foreach (FileInfo f in files)
{
// read the whole thing, do something
}
....
}

Thank you very much for your help
