Make the format work for you

Use it to ship copy-and-paste ready snippets in onboarding docs or customer success playbooks.

Normalize line endings and explicit UTF encodings when sharing across operating systems.
Text files rarely carry threats, but scripts can execute commands. Review before running.
Add a short README alongside the file so collaborators know when to use it and how to preview it.

Quick operational checklist

Share confidently. Include sample content and note the expected software version so reviewers open it correctly.
Stay searchable. Tag uploads with text/x-c or .c in your knowledge base so teammates find the right asset fast.
Plan conversions. If recipients cannot open .c, export a lightweight PDF or screenshot alternative for quick review.

Explore neighbours to decide whether .c is the best hand-off or if a sibling suits your workflow better.
