Untracked Files
When you create a new file, Git doesn't track it until you add it manually.
git status
New files will appear under Untracked files in red.
Track a New File
Use git add to start tracking a new file:
git add filename.txt
Track All New Files
You can add all new files at once with:
git add .
Check Status After Adding
git status
Now the file will appear under Changes to be committed in green.
Commit New Files
Once added, commit the files with a message:
git commit -m "Add new file"
