folder and filename
Drafts are posts without a date in the filename. They’re posts you’re still working on and don’t want to publish yet.
To get up and running with drafts, create a _drafts folder in your site’s root and create your first draft:
.
├── _drafts
│ └── a-draft-post.md
...run
To preview your site with drafts, run jekyll serve or jekyll build with the --drafts switch.
Time
Each will be assigned the value modification time of the draft file for its date, and thus you will see currently edited drafts as the latest posts.
