The code I posted in one of your previous threads seems to be working OK for all those formats: using System; using System.Text.RegularExpressions; class Test { static void Main() { string[] fileTemplates = { abc_{yyyyMMdd}_xyz_{HHmmss} abc_{yyMMdd_HHmmss} abc_{yyMMdd_HHmmsstt} abc_{yyyyMMdd}_xyz_{HHmmss} abc_{yyyyMMdd_HHmmss}_xyz abc_{yyyyMMdd_HHmmsstt} }; foreach(string fileTemplate in fileTemplates) { string f = GetFileNameFromTemplate(fileTemplate); Console.WriteLine(f); } Console.ReadKey(); } static string GetFileNameFromTemplate(string fileTemplate) { DateTime now = DateTime.Now; string r = @\{(.*?)}; string f = Regex.Replace(fileTemplate r m => now.ToString(m.Groups[1].Value)); if (!f.EndsWith(.txt)) f += .txt; return f; } } The output when I just ran it (UK time) was: abc_20140825_xyz_183604.txt abc_140825_183604.txt abc_140825_183604PM.txt abc_20140825_xyz_183604.txt abc_20140825_183604_xyz.txt abc_20140825_183604PM.txt

iteration for this "abc_{yyyyMMdd}_xyz_{HHmmss}" filename.
