Here is an example of solution using both Regex and string class methods. In Regex I use a group with "FileCode" name to get result.
As Pete said not all cases require using of Regex. And in this case I think would be better to use string methods (alternative variant).
const string pattern = @"_(?<FileCode>([^_][a-zA-Z0-9])+)\.txt$";
const string text = @"Directory\Subdirectory\Subdir\Subsubdir\sub_sub_subv009\filename_with_lots_of_ABC123.txt";

var groupFileCode = Regex.Match(text, pattern);

Console.WriteLine(groupFileCode.Groups["FileCode"].Value);

// alternatively without regullar expressions
int lastUnderscoreIndex = text.LastIndexOf('_');
int lastPointIndex = text.LastIndexOf('.');

Console.WriteLine(text.Substring(lastUnderscoreIndex + 1, lastPointIndex - lastUnderscoreIndex - 1));

Regards, savbace
