The Vault File Renamer plugin helps maintain a consistent file naming structure within an Obsidian vault by automatically standardizing filenames. It ensures uniformity by converting filenames to lowercase, removing accents, and replacing spaces with dashes. The plugin enforces a naming convention that aligns with GitHub's standards, allowing only letters, numbers, and specific symbols while converting disallowed characters. It operates seamlessly in the background, automatically renaming files upon creation or manual renaming.
