Deleting untracked files in Git helps clean your working directory by removing temporary files, build artifacts, and other unwanted content not tracked by Git. As the creator of CoreUI with over 25 years of development experience, I regularly clean untracked files to maintain organized repositories and prevent accidental commits. The most reliable approach uses git clean with appropriate flags to remove untracked files and directories safely. This command provides precise control over what gets deleted while protecting important untracked content.
