Doubt when joining txt files

Question

Searching the internet to join txt files, I found the command line code CMD below:

for %f in (*.txt) do "%f" >> união.txt

The logic is to make a loop, grab all the txt files and create a new file 'union.txt' with all of them together.

The same does not work, it opens all the files and creates the new, but the new is blank.

Any hint?

Answer 1

I can solve this way:

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

The code says the following:

for %f in (*txt) //loops all files. txt

do type //the type command was missing he is the write command

"%f" >> união.txt //writes the contents of the files inside the.txt union file

Answer 2

Use a copy /Bignaria:

copy /B *.txt unir.txt
