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

[Lakesider]

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

Use the System.IO.FileSystemWatcher class.

Use the System.IO.FileSystemWatcher class.

And in the Created FileSystemEventHandler i would use try/catch with
File.OpenRead to see if it's ready.

Thank you,

but which Event is the right for me?
It should fire if a large file is beeing copied successfully to my
folder.

Thank you
