So when it comes to time to save it, read the folder it is going to, and look at tahe names:

C#

string[] paths = Directory.GetFiles(@"D:\Temp\", @"file*.txt");

You can then work out the highest current number from that:

C#

int max = 0;
foreach (string path in paths)
    {
    string justTheName = Path.GetFileNameWithoutExtension(path);
    Match m = Regex.Match(justTheName, @"\d+$");
    if (m.Success)
        {
        int i = int.Parse(m.Value);
        max = Math.Max(max, i);
        }
    }
string newFileName = string.Format(@"D:\Temp\file{0}.txt", max + 1);
