 # How do I make Git forget about a file that was tracked, but is now in .gitignore?
 
-First:
+`.gitignore` will prevent untracked files from being added (without an `add -f`) to the set of files tracked by Git. However, Git will continue to track any files that are already being tracked.
 
-```bash
+To stop tracking a file, we must remove it from the index:
-git rm -r --cached .
+
-git add .
+    git rm --cached <file>
-``` 
+
+To remove a folder and all files in the folder recursively:
+
+    git rm -r --cached <folder>
+
+The removal of the file from the head revision will happen on the next commit.
+
+**WARNING: While this will not remove the physical file from your local machine, it will remove the files from other developers' machines on their next `git pull`.**

-Then:
 
-```bash
-git commit -am "Remove ignored files"
-```
 
-Or as a one-liner:
 
-```bash
-git rm -r --cached . && git add . && git commit -am "Remove ignored files"
-```
