Capitalization in Titles and Headings

Published on December 22, 2015 by Sarah Vinz. Revised on June 20, 2022. https://www.scribbr.com/academic-writing/capitalization-titles-headings/

There are three main options for capitalizing chapter and section headings within your dissertation:

1. capitalizing all significant words
2. capitalizing only the first word
3. a combination of the two

Option 1: All significant words capitalized

Rules for Naming Files and Folders that are Cross Platform

Use styles that are internationally recognized, easy to read by a human eye, and require fewer finger movements on the keyboard, for example, using lowercase letters that eliminate the shift key.

1. Use all lowercase letters.
2. Use hyphens (not underscores) to separate words. Avoid using spaces as they are difficult to work with on the command line.
3. Use YYYY-MM-DD format for dates. It is adapted from https://www.iso.org/iso-8601-date-and-time-format.html.
4. While using the date at the beginning of a file name, keep the rest of the file name the same as the one created on a previous date (if there is more than one file for the same purpose, but it is sectioned according to the date.)
5. Use "." only for file extensions.
6. Use v1, v2, ..., vn to denote file versions.
