The External File Embed and Link plugin allows Obsidian users to embed and link files located outside their vault using relative paths. It supports a variety of file types, including PDFs, images, audio, and videos, ensuring compatibility across devices and platforms. Users can reference files relative to the Home or Vault directory, which is particularly useful for cross-platform workflows. The plugin includes features such as drag-and-drop support, customizable embedding options, and commands for creating file links or embeds via a file picker. Additional parameters enable users to control the display of embedded content, such as PDF page numbers or image dimensions, making it a versatile tool for integrating external resources into Obsidian notes.
