Open an MS-DOS window. You want to put file1.txt at the end of file2.txt Type in the command: type file1.txt >> file2.txt Alternatively, just use a good text editor, use select all on file1.txt, copy, switch to file2.txt, put the cursor where you want to, and paste. Those are the simple methods. It gets tedious with a lot of files, and I expect that's why you want something more from the software.
