Why can't I add this directory to git?

Question

$ git add . ; git add *; git status
# On branch master
nothing to commit (working directory clean)

My folder is in there, but I can't add it.

Answer 1

By any chance, is the directory blank? You can't add directories to git.

Answer 2

I know this question is quite old now and the answer has been accepted but I had a similar problem where I couldn't add a directory.

In my case the problem was that I didn't have permission to access the directory. I changed the permissions and then I was able to add it.
