I need to add some binary files to a Git repository for some time.
(Actually they are ODT documents that I want to consecutively convert to versionable LaTeX source files. I want them in the repo because I work on several computers and also share some work with others).
But I want these binary files to be removed once I don't need them anymore.
Probably it isn't a real problem, but for consistency I'd prefer having them purged from the repo.

So what I thought is to create a new branch and add the binary files to it, so all commits with these files are in the context of this single branch.

If I then delete this branch with `git branch -D`, do these files disappear or will they still be in the repo as part of its history?
