Hi guys what is the meaning of double back slash in my Git folder? It is not removed when I do a "git clean -fd". This is the first time I encountered something like this.

$ git status
On branch master
Changes not staged for commit:
(use "git add <file>..." to update what will be committed)
(use "git checkout -- <file>..." to discard changes in working directory)

modified: some/folder/hello.php

Untracked files:
(use "git add <file>..." to include in what will be committed)

"\\"

no changes added to commit (use "git add" and/or "git commit -a")
