The Update Relative Links plugin addresses issues with Obsidian's default implementation of automatic internal link updates. It ensures that all links in a moved file, including references to other files, are correctly updated to maintain relative paths. This plugin offers two main features: automatic correction of relative paths upon file movement and a batch fix command to update links across all files in the vault. By using Markdown's link syntax, the plugin enhances note portability and compatibility with other Markdown editors and platforms.
