ValidTitle

A lightweight, zero-configuration plugin that automatically sanitizes invalid Windows filename characters inside wikilinks ([[...]]) preventing Obsidian's annoying "File name cannot contain..." error popup.

How it works

When you type or click on a link with an illegal character (like [[French Revolution: Causes?]]), ValidTitle intercepts the link creation and automatically fixes it to [[French Revolution - Causes]] in a millisecond.

It safely ignores aliases (|), markdown tables, code blocks, and headings (#).

Replaces:

• : with -
• / \ | with -
• removes * ? " < >

Usage

Just enable the plugin. There are no settings, no ribbons, and no commands. It simply works silently in the background.
