Column Explorer

Column Explorer replaces Obsidian's file tree with Finder-style Miller columns. Clicking a folder opens its contents in a new column to the right, so the path you came through stays on screen instead of scrolling away inside one narrow list. It works as a full file manager: create, rename, move, delete, drag and drop, multi-select, context menus, folder colors and icons, pinned and starred folders. The first column can also carry virtual rows for recent files, core-plugin bookmarks and a month calendar with per-day counts of notes created. A sunburst chart reports vault disk usage by size, word count or file count.

Why you might want this

Obsidian's built-in file explorer is a single vertical tree. That works for twenty notes. At two hundred folders it stops working: expanding one branch pushes everything else off-screen, collapsing it loses your place, and you scroll a column one item wide looking for a file you already know the name of.

Miller columns fix this by spending horizontal space instead of vertical. Each level of the hierarchy gets its own column, side by side — you see where you are, where you came from, and what's next, all at once. It's how Finder's column view and NeXTSTEP's file browser have worked for thirty years, because for deep trees it's simply easier to read.

On top of that, Column Explorer lets you star the folders you actually live in, so the paths you open twenty times a day are one click away instead of five.

If your vault is flat and small, the default explorer is fine. If you keep a deep folder structure and lose files in it, this is for you.

Installation

Community plugins (recommended)

Settings → Community plugins → Browse, search for Column Explorer, install and enable.

Manual

1. Download main.js, manifest.json and styles.css from the latest release
2. Copy them into <vault>/.obsidian/plugins/column-explorer/
3. Enable the plugin in Settings → Community plugins

Getting started

1. Open it — click the columns icon in the left ribbon, or run the command Open column explorer. The view opens in the left sidebar.
2. Click a folder — its contents appear in a new column to the right. Keep clicking to drill down; the breadcrumb bar above shows the full path and jumps back to any level.
3. Make it yours — right-click a folder for colors, icons and Pin to top; click the star in the breadcrumb bar to add the current folder to Favorites; drag the right edge of a column to resize it.

Worth knowing early: Space previews the selected file, right-clicking empty space creates a note or folder there, and Settings → Column Explorer has a Special items section that turns on the Recents, Bookmarks, Calendar and Disk usage rows.

Highlights

• Miller columns — Finder-style navigation, each folder opens a new column
• Recents, Bookmarks & Calendar — virtual rows in the first column: recently opened files (up to 50), your core-plugin bookmarks, and a month calendar with per-day created-note badges — click a day to list the notes created then
• Disk usage — a sunburst chart of the vault by size, word count or file count, with animated zoom into any folder
• Import from the OS — drop files from Finder/Explorer into any column to copy them into the vault
• Folder colors, icons and pins — eight theme-aware colors, any lucide icon, pin items to the top
• List or icon grid per folder — the grid shows real image thumbnails
• Quick Look & preview column — Space previews the selected file; optional details column with media previews
• Resizable everything — per-column widths, auto-resizing side panel, lockable column count
• Full file manager — multi-select, drag & drop with undo, context menus, per-folder sort, excluded files
• Built for phones too — one column at a time, a compact toolbar, long-press multi-select, edge-swipe navigation and an adjustable interface scale

Features

Navigation

• Miller columns — drill down through folders, each level in its own column
• Sidebar or main area — a setting opens the view as a full-width tab instead of the left sidebar
• Breadcrumbs — clickable path bar for quick jumps to any ancestor folder
• Folder notes — optionally open the note named like its folder when selecting the folder
• Keyboard navigation — ↑/↓ select, →/← drill in/out, Home/End/PageUp/PageDown, type-ahead (start typing to jump, like in Finder), Enter open, Space Quick Look, F2 rename, Delete trash, Ctrl/Cmd+A select all in the column, Ctrl/Cmd+D duplicate, Ctrl/Cmd+C/X/V copy, cut and paste
• Back & forward — navigation history buttons in the breadcrumbs bar
• Favorites — star any file or folder (context menu, or the star button in the breadcrumbs bar); they sit atop the Bookmarks column
• Filter — live search box that filters files in every column
• Auto-reveal — optionally follow the active editor tab
• Persistent state — selected path survives app restarts

Special items

The first column can host four virtual rows, each toggleable and positionable in settings.

• Recents — the last files you opened, up to 50
• Bookmarks — your core Bookmarks plugin items, with Favorites pinned above them
• Calendar — a month grid with a badge per day showing how many notes were created then; click a day to list them
• Disk usage — an interactive sunburst chart of the whole vault, in the spirit of classic disk-usage analyzers. Switch between size (bytes on disk), words and files; click a folder to fly inside it, Esc or the centre circle to go back out, and click a file to open it. Sectors too thin to see merge into one muted "small items" arc, hovering highlights a folder with all of its descendants, and the chart rescans itself when the vault changes. Excluded folders and the number of visible rings are configurable.

Appearance

• List or icon view per column — toggle in the column header, remembered per folder
• Image thumbnails — the icon view shows real thumbnails for image files
• Folder colors & icons — right-click a folder: eight theme-aware color presets and any lucide icon
• Pinned items — right-click → Pin to top; drag one pin onto another to reorder
• File preview column — image, audio, video and PDF previews, note content, size, dates
• Unread markers — a small New badge on files you have never opened, and a dot on files edited since you last opened them (by an agent, a bot, sync or an external editor). Opening a file clears both; the whole thing can be switched off in settings
• Item counts — each column header shows how many items it lists
• Resizable columns — drag the right edge of any column
• Localized — English, Chinese (Simplified), German, Japanese, Korean, Brazilian Portuguese, Spanish, French, Italian and Russian, following Obsidian's own language setting

File management

• All standard operations — create notes, canvases and folders (with inline rename), rename, trash, duplicate, move to folder, copy path
• Multi-select — Ctrl/Cmd-click to toggle, Shift-click for range; move, duplicate, delete or drag many at once
• Copy, cut & paste — Ctrl/Cmd+C/X/V or the context menu; paste lands in the current folder (or the right-clicked one), name clashes get a numeric suffix, cut items are dimmed until pasted
• Drag & drop — move files/folders between columns, straight onto a folder row or onto a breadcrumb segment; drag a file into an editor to insert a link
• Full Obsidian context menu — core & community plugin items (bookmarks, "Reveal in Finder", copy link, …) are injected via the file-menu event
• Copy links & paths — vault path, absolute system path, wikilink, Markdown link or obsidian:// URL, from the context menu
• Excluded files — hide files and folders by comma-separated patterns. *.tmp matches by file name at any depth (* is any run of characters, ? exactly one); .trash matches any path containing it; a trailing slash (archive/) is a path prefix from the vault root, so nested folders need their full path (Notes/archive/)
• Sort options — global default plus per-folder overrides (right-click a column header): name, modified, created or size, both directions

Mobile

The plugin works on Android and iOS, with a layout of its own — desktop behaviour is unchanged.

• One column at a time — the deepest folder fills the screen; an up arrow in the column header walks back out
• Compact toolbar — back, forward, search, create and a more menu (reveal, collapse, sort)
• Long-press to select — hold an item to enter selection mode, then tap to add more; a bottom bar moves, duplicates, deletes or opens the full menu
• Edge swipe — swipe in from the left or right edge to go back or forward
• Quick Look instead of a preview column — open Preview from a file's menu; it slides up as a sheet
• Adjustable scale — Settings → Mobile interface: interface scale (90–150%) and icon size (22–36px), applied live. Touch targets never drop below 44px
• No drag & drop — on touch screens it fights with scrolling; move files through selection mode instead

Commands

All are bindable to hotkeys in Settings → Hotkeys.

FAQ

Does it replace the built-in file explorer? No — it's a separate view, and both can be open at once. Most people disable the core File Explorer afterwards, but that's your call.

Can I open it as a full-width tab instead of in the sidebar? Yes — Settings → Column Explorer → Where to open switches the open command and the ribbon icon to a tab in the main area. An already open view is never moved, so you can also just drag its tab wherever you like.

Why doesn't drag & drop work on my phone? Deliberately disabled: on touch screens a drag gesture competes with scrolling. Long-press an item to enter selection mode, then use the bottom bar to move files.

How do the exclude patterns work? Comma-separated. *.tmp matches by file name at any depth — * stands for any run of characters and ? for exactly one, so draft-?.md hides draft-1.md but not draft-12.md. .trash matches any path containing that string, and a trailing slash (archive/) is a path prefix from the vault root — so a nested folder needs its full path, e.g. Notes/archive/.

Does it work with Folder Notes / Iconize / other explorer plugins? Column Explorer has its own folder-note and folder-icon support built in, so you don't need those for this view. Plugins that decorate the core file explorer won't affect this one — but any plugin that adds items to Obsidian's file context menu shows up here too, because the menu is built from the same file-menu event.

Will renaming or moving files here break my links? No. All operations go through Obsidian's own fileManager, the same API the core explorer uses, so links and backlinks are updated for you.

Is my vault too big for it? Large folders render in chunks as you scroll, so tens of thousands of files are fine. If a specific vault feels slow, please open an issue with the size and shape of it.
