miauu's Folder Bookmarks enhances the default Open, Save, Import, Export, Merge, and Replace dialogs in 3ds Max. Rather than opening separate tools or browsing through folders repeatedly, your saved bookmarks appear directly inside these native dialogs. You can save and manage custom bookmarks either globally or per scene.
Global bookmarks store any folder for access at all times, across all scenes and file dialogs. Local bookmarks are scene-specific and saved directly in the .max file, so they are only available while that scene is open. A Current File Folder shortcut jumps to the folder where your currently opened .max file lives, straight from the file dialogs. You can also sort recently opened and pinned files by name or last accessed date.
The Bookmark Manager handles organization: rearrange bookmarks, sort them alphabetically, add or remove entries, and clear out all invalid (non-existent) bookmarks in one step. Global and local bookmarks display separately, invalid ones show in red, and a right-click opens any bookmark's folder in Windows File Explorer.
