git copy [branch]中的文件，并粘贴到其他[branch or master]下

Question

I created repository as following ...,

TestRepo.git
    |
    |_[Branch.Master]
             |____________Master.txt
    |_[Branch.Develop]
             |____________Develop.txt

I want to copy Develop.txt and paste under [Branch.Master] .

/// So I checkout Develop first.
$ git checkout Develop
/// Then I push develop.txt to remote/master
$ git push origin develop:master
/// Then I pull remote/master to my local/master.

Then I got below result which is not what I want.

TestRepo.git
    |
    |_[Branch.Master]
             |____________Develop.txt
    |_[Branch.Develop]
             |____________Develop.txt

What I want is like below.

TestRepo.git
    |
    |_[Branch.Master]
             |____________Master.txt
             |____________Develop.txt
    |_[Branch.Develop]
             |____________Develop.txt

I don't want to be replaced, what I want is just append.

I appreciate your suggestion(s).

If all you want to do is to add a new file, you can simply copy the file from the source branch to the target branch.

git checkout master
git checkout Develop Develop.txt

Then add the file, commit it, and push the branch out.

git add Develop.txt
git commit -m 'Added Develop.txt to the master branch'
git push origin master
