After deleting file and re-creating file, not change creation date in windows

Question

I have c# application. This write log in folder.

below code.

if (File.Exists(@"C:\EXT_LOG\LOG.txt"))
{
    File.Delete(@"C:\EXT_LOG\LOG.txt");
}

string Data = "xxxxx";
System.IO.StreamWriter file = new StreamWriter(@"C:\EXT_LOG\LOG.txt");
file.WriteLine(Data);
file.Dispose();
file.Close();

I delete file, if it exist, and I create file with same name. when I run program, the creation date of file is not change.

I guess windows any manager or any file table still contain that file.

So, when I delete file, can I delete manager or file table content??

Answer 1

That's how it works in windows. I have not searched Google for WHY. However it seems you can set the creation date of the file through C# using System.IO.File.SetCreationTime method.

public static void SetCreationTime(
    string path,
    DateTime creationTime
)
