# Folder Watching

Drop a folder of plain-text notes onto Marked. Marked opens a preview window that always tracks the most recently edited eligible file inside that folder (.md, .txt, .markdown, etc., matching Marked’s file-type filters).

Updates run whenever any watched file saves: if the newest file matches the previous one, Marked scrolls toward the detected edit region; when you switch documents, the entire preview swaps to the active file.

## Works well with nvUltra, nvALT, and similar tools

Notebook apps that leave individual files on disk (classic nvALT, nvUltra, Notational Velocity-style libraries, synced Git folders, Dropbox scratch folders, etc.) pair naturally with folder watching—you write in one window and keep Marked pinned beside it without manually reopening previews.

nvUltra also offers Preview File(s) in Marked in its contextual menu when you want to open specific notes in Marked directly instead of attaching Marked to the whole-folder watcher flow described above.

Marked also exposes the same watcher behavior under other menu names when you consolidate many small chapters into what feels like one reading experience; see also Multi-File Documents for manuscripts that intentionally merge multiple Markdown sources.
