deleting a file generates Exception "could not find a part of the path"

I want to delete a Directory and all its files and it has files/Directories with a very long path.

The file I'm trying to delete has a long path (longer than 260 characters).

How can I delete this file in spite of its length? I'm using the following code:

foreach (string archiveFolder in Archives)
{
    try
    {
        DateTime creationTime = Directory.GetCreationTime(archiveFolder);
        DateTime now = DateTime.Now;
        DateTime passDate = creationTime.AddDays(numDaysBack);
        if (passDate.CompareTo(now) < 0)
        {
            try
            {
                Directory.Delete(archiveFolder, true);
            }
            catch (Exception e)
            {
            }
            //System.Console.WriteLine(creationTime);

        }
    }
    catch (Exception e)
    {
    }
}

I fixed the problem of having a file with long path down inside the directory structure of the directory I'm deleting by prepending \\?\ (long path specifier) to the Directory.Delete argument.

So in your cause it would be

   Directory.Delete(@"\\?\" + archiveFolder, true);

Directory.Delete is meant to delete directories, to delete files use File.Delete

They both reside in System.IO, the change should be trivial.
