From the developer:
Concatenating multiple text files into a single file can be a tedious task, especially if the files reside in different directories. FileConcatenator is a powerful GUI utility that provides the ability to quickly concatenate multiple files. You simply add your files in the application GUI, choose your destination folder and file and let the program do the rest.
