Hi You can use below functions for that - private static string numberPattern =  ({0}); public static string NextAvailableFilename(string path) { // Short-cut if already available if (!File.Exists(path)) return path; // If path has extension then insert the number pattern just before the extension and return next filename if (Path.HasExtension(path)) return GetNextFilename(path.Insert(path.LastIndexOf(Path.GetExtension(path)) numberPattern)); // Otherwise just append the pattern to the path and return next filename return GetNextFilename(path + numberPattern); } private static string GetNextFilename(string pattern) { string tmp = string.Format(pattern 1); if (tmp == pattern) throw new ArgumentException(The pattern must include an index place-holder pattern); if (!File.Exists(tmp)) return tmp; // short-circuit if no matches int min = 1 max = 2; // min is inclusive max is exclusive/untested while (File.Exists(string.Format(pattern max))) { min = max; max *= 2; } while (max != min + 1) { int pivot = (max + min) / 2; if (File.Exists(string.Format(pattern pivot))) min = pivot; else max = pivot; } return string.Format(pattern max); } Now make some changes in your code as below - Bitmap bitmap = new Bitmap(Screen.PrimaryScreen.Bounds.Width Screen.PrimaryScreen.Bounds.Height); Graphics graphics = Graphics.FromImage(bitmap as Image); graphics.CopyFromScreen(0 0 0 0 bitmap.Size); var date = DateTime.Now.ToString(dd-MM-yyyy); string format = txtname.Text += date; string filepath = NextAvailableFilename(@E:\Project backups\Medical\Sales_receipt\ + format + .jpg); bitmap.Save(filepath System.Drawing.Imaging.ImageFormat.Jpeg); Please refer below link for more details - http://stackoverflow.com/questions/1078003/c-how-would-you-make-a-unique-filename-by-adding-a-number
