I dont even know if this will compile (Im on my Mac at the moment) - but I'd be trying something like

// Needs uses System.IO;

string folderPath = "Your File Folder Here";

if (Directory.Exists(folderPath))
{
	DirectoryInfo di = new DirectoryInfo(folderPath);

     // Get only the xlsx files excluding One We Don’t Want
     List<string> xlsxFiles = di.GetFiles("*.xlsx")
                              .Where(file => !(file.Name.EndsWith("testFile.xlsx")))
                              .Select(file => file.Name).ToList();

	foreach (string filenameToDelete in xlsxFiles)
	{
                // Archive File Goes Here
                // Then Delete It 
		File.Delete(filenameToDelete);
	}
}
