Copy text files into one file including filenames

Question

From the Windows command prompt it's possible to collect all text files into one file using

copy *.txt all_text_files.txt

Is it possible to add the name of each file added in front of the file in question? In my example I have two text files a & b.

a.txt consists of one line:

Cheese

b.txt also consists of one line:

Monkeys

The new file would be:

a.txt
Cheese
b.txt
Monkeys

See this answer. I think its relevant: http://stackoverflow.com/a/2477341/445695 — pantuofermo, Apr 13 '16 at 13:38

If you write it directly in the command line, this should work. If you want to make a script I believe you need to put double %

for %f in (*.txt) do (
    echo "%f"
    type "%f"
) > all_text_files.txt

Not sure if that works with files with spaces in the name – Mr Mystery Guest Apr 13 '16 at 13:54
It doesn't, but you just need to add `"`. I edited my answer. – Nico Apr 13 '16 at 14:05

type *.txt >allfiles.out 2>&1
ren allfiles.out allfiles.txt

type types all matching files. The file contents goes to STDOUT, the filenames are printed to STDERR. So just redirect both to the new file. Choose a different extension to avoid recursive handling.
