File Management

File Browser

Open a folder with File > Open (Cmd O) to see its tree in the left sidebar. Click files to open them in a tab, click folders to expand or collapse them.

Toggle the file browser with Cmd 1. Its width is adjustable between 150 and 350 pixels.

Searching

Click the magnifying glass icon in the file browser header to reveal a search field. Type to filter files by name (case-insensitive). Results show the filename and relative path. The search debounces at 200ms, so it updates smoothly as you type.

Context Menu

Right-click any file or folder for these actions:

• New File — creates an Untitled.md file (auto-incrementing: Untitled 2.md, etc.) and opens it for editing with the name pre-selected for renaming
• New Folder — creates a New Folder directory (auto-incrementing)
• Show in Finder — reveals in macOS Finder
• Copy — copies the file to the clipboard
• Copy Path — copies the full file path
• Copy Relative Path — copies the path relative to the browser root
• Duplicate — creates a copy with a "copy" suffix (or "copy 2", etc.)
• Rename — activates inline editing of the filename (press Return to confirm, Escape to cancel, or click away to auto-save)
• Delete — moves the file to Trash

Right-click the empty space at the bottom of the file browser to create a new file or folder in the root directory.

Drag and Drop

Drag files between folders in the browser to reorganize. The cursor changes to a move arrow. You can also drag external files from Finder into the browser to move them into your project folder.

Sorting

In Settings, you can configure two sorting options:

• Keep folders on top (on by default) — folders always appear above files
• Known formats first (off by default) — files that Quindin can edit (Markdown, plain text) sort above other file types

Within each group, files are sorted alphabetically (case-insensitive).

Directory Watching

Quindin watches the open folder for changes on disk. If you create, move, rename, or delete files outside the app, the browser updates automatically (with a 150ms debounce to avoid flicker).

Tabs

Each file opens in its own tab. Tabs preserve their cursor position, selection, and outline state, so switching tabs restores exactly where you left off.

Tabs can be reordered by dragging. Navigation wraps around — pressing Next Tab on the last tab jumps to the first.

Tab Context Menu

Right-click a tab for additional options:

• Close — close this tab
• Close Others — close all tabs except this one
• Close Tabs to the Right — close tabs after this one
• Close All — close every tab
• Copy Path — copy the file's full path
• Reveal in Finder — open the file's location

If any tab being closed has unsaved changes, you'll be asked to Save, Don't Save, or Cancel — individually for each modified tab.

Favorites

Star any file to add it to Favorites. Favorites appear in two places:

• The Welcome screen — a dedicated Favorites section at the top of the right column
• Quick Open (Cmd P) — when the search field is empty, favorites are shown first

To star a file, hover over it in the Welcome screen's recent files list and click the star icon.

Recent Files

Quindin remembers your 20 most recently opened files. Access them from File > Open Recent or from the Welcome screen. Quindin uses security-scoped bookmarks to remember folder permissions across restarts — once you grant access to a folder, you won't be asked again.

Other File Operations

Duplicate creates a copy of the current file on disk (with a "copy" suffix) and opens it. For unsaved files, it creates a new tab with the same content but no file URL.

Revert to Saved discards your in-memory changes and reloads the file from disk.
