combine text files using command line script in Windows

Question

Do you know somehow to achieve this in Windows?

I am thinking about a few commands that will combine all the txt files in a directory into a single one.

Answer 1

You can also use the copy command, eg

copy *.js bigfile.txt

or, for specific files

copy file1.txt+file2.txt+file3.txt bigfile.txt

Answer 2

type * > someotherpath/all.txt

The need for creating the file somewhere else is that if the new file is created on the same folder, it should be excluded from the selection.

Also, filtering by extension and using a different one for the resulting file would work. For example:

type *.js > all.txt
