What can be "untracked files' in Git?

Tracked files are files in the last snapshot. And everything else is untracked files.

So what can be a untracked file, besides newl开发者_如何学运维y created files?

I'm not sure I quite understand your question, but there's no requirement that each commit ("snapshot") includes every file that was in the working directory when that was created. Your untracked file might have been in your working directory for a long time, and just never have been added.
