The External File Card plugin enhances Obsidian by providing an intuitive way to reference files stored outside your vault. It allows users to display detailed cards or create inline links for external files and folders using customizable code blocks or Obsidian URIs. These cards include file names, paths, creation dates, and modification dates, with clickable links to open files or folders in default system applications. The plugin supports multiple root paths for file searching, customizable display text, and efficient handling of spaces in file names. Designed for accessibility across devices, it is particularly useful for users managing external documents stored in cloud services like OneDrive.
