Hi .. try this tep 1 : as a first step identify wether the file exists or not before copying the file. using File.Exists() method Step 2: if the file already exists with same name then delete the existing file using File.Delete() method Step 3: now copy the File into the new Location using File.Copy() method. Step 4: Rename the newly copied file. Try This: string NewFilePath = Path.Combine(NewFileLocation, fileName); if(File.Exists(NewFilePath)) { File.Delete(NewFilePath); } //Now copy the file first File.Copy(FileLocation, NewFileLocation, true); //Now Rename the File File.Move(NewFilePath, Path.Combine(NewFileLocation, "File.txt"));
