How To Archive on filename characters (Underscores vs. Hyphens)

This short video from How To Archive is more of a personal convention note than a technical breakdown. Photographer Michael Grecco briefly explains when he chooses underscores or hyphens in filenames. The main focus is making files compatible and readable across systems, with a nod to SEO practices when putting images online.

Steps to follow

  1. Use underscores instead of spaces when naming files for internal storage
  2. Use hyphens when naming files for web publishing or SEO

Advice

  • Avoid spaces in filenames to ensure compatibility across systems
  • Use SEO-friendly naming (e.g. actor-steve-martin-by-photographer-michael-grecco.jpg) when putting files on the web
  • For internal use, choose one convention and stick with it—underscores in this case
  • There’s a difference between what’s readable for a system and what’s searchable online
