Depends on whether you want to overwrite the files written from an older for loop. If this is the case, then you can just write the filename as @"D:\Temp\File.xml"+i If you don't want to overwrite files at all, then you'd first have to examine all filenames in the directory (via Directory.GetFiles()) and get the highest file id ever assigned, and start the counter from there. regards

@"D:\Temp\File" + i + ".xml" is probably more useful.

Use a GUID for a filename - they're guaranteed to be unique, and therefore aren't susceptible to stopping/restarting the program.

for (int indx = 0; indx < contact.Fields.Count; indx++)
{
string guid = Guid.NewGuid().ToString().Replace("-","").Replace("{","").Replace("}","");
StreamWriter sw = new StreamWriter(string.Format("D:\\Temp\\{0}.xml", guid));
sw.WriteLine(contact.Xml);
sw.Flush();
sw.Close();
}

If you don't want to delete the hyphens or curly braces, remove the Replace() method calls.
