An old DOS trick to create a file is to run "copy con newfile.txt" and hit enter. Then you can start typing the file's contents. I don't recommend trying to use backspace or delete since it doesn't always work like you think, depending on your shell. When you're done, hit F6 or Ctrl+Z followed Enter. It still works in cmd.exe. Similarly, you can create an empty file with "copy nul newfile.txt" or test copy a file with "copy filename.txt nul".
