How do I merge 2 text files into one file?

问题:

Okay so, I want to merge 2 text files :

File 1 :

Firstline
ABCD
Thirdline

Fifthine

File 2 :

Firstline

Thirdline
EFGH
Fifthline

Expected output :

Firstline
ABCD
Thirdline
EFGH
Fifthline

I can't use copy filea+fileb filec with cmd because it just copy and paste one to another and merge it into one file.

Try the following procedure with notepad++:

1. Go to file1 and add some data that cannot be found on the lines (for example @@@@@) at the beggining of each line with following regex replace: search (regex): ^ Replace by: @@@@@. After that, first file should look like this:

   @@@@@Firstline
   @@@@@ABCD
   @@@@@Thirdline
   @@@@@
   @@@@@Fifthine
   

2. Go to second file and select (as columns) all data. You can do this placing at the beggining of the file and the ALT+SHIFT+(END, PAGEUP)

3. Control+C for copy

4. Go to first file, place at the beggining and paste with Control+V. The first file now should look like this:

   Firstline@@@@@Firstline
   @@@@@ABCD
   Thirdline@@@@@Thirdline
   EFGH@@@@@
   Fifthline@@@@@Fifthine
   

5. Do a search and replace: Search (regex): ^@@@@@|@@@@@[^\n\r]* Replace: (nothing). The first file will be:

   Firstline
   ABCD
   Thirdline
   EFGH
   Fifthline
