Answer 2

If the file is already added in to repository then you need to remove them. Git thinks of its data more like a set of snapshots of a miniature filesystem. Every time you commit, or save the state of your project in Git, it basically takes a picture of what all your files look like at that moment and stores a reference to that snapshot. To be efficient, if files have not changed, Git doesn't store the file again, just a link to the previous identical file it has already stored. Git thinks about its data more like a stream of snapshots. So you need to remove the already added files then

git rm --cached file-1 file-2..... file-n

Then the files listed in gitignore will work as expected. Check the notes section in the Git Documentation
