I created a git repository with
Git keeps all of its files in the
.git directory. Just remove that one and init again.
If you can't find it, it's because it is hidden.
In Windows 7, you need to go to your folder, click on Organize on the top left, then click on Folder and search options, then click on the View tab and click on the Show hidden files, folders and drives radio button.
On a Mac OS:
Open a Terminal (via Spotlight: press CMD + SPACE, type
terminal and press Enter) and do this command:
defaults write com.apple.finder AppleShowAllFiles 1 && killall Finder.
Or you could also type
cd (the space is important), drag and drop your git repo folder from Finder to the terminal window, press return, then type
rm -fr .git, then return again.
On Ubuntu, use shortcut Ctrl + H.
