Using mairok

The window

• Toolbar: back / forward / parent, the breadcrumb (click it to type a path), open Terminal, Grid · List · Preview toggles, theme and icon size
• Sidebar: This Mac (the drive list) first, then standard folders (Home, Desktop, Documents, …), a Pinned group and Locations (drives)
• Files: grid or list, folders first, then natural name order (file2 before file10)
• Preview: a fixed-width panel on the right
• Status bar: item count, selection, and copy progress

Preview

Select one file and the right panel shows

• Images: png, jpg, gif, webp, bmp, ico, tiff
• Text / Markdown / code: the first 64 KB
• Metadata: kind, size, created, modified, and image dimensions

PDF, video and audio open in an external app. On macOS, Space opens Quick Look.

Selecting

• Click to select, ⌘-click to add, Shift-click for a range
• Drag on empty space for a rubber-band selection
• Type letters to jump to a matching name
• Tab moves keyboard focus between the sidebar and the files

Copy, move, delete

• ⌘C / ⌘X then ⌘V. The clipboard is in-app only (not shared with Finder / Explorer yet).
• Drag files onto a folder to move them; hold Alt while dragging to copy
• Drops from Finder / Explorer copy
• Name clashes ask Replace, Keep Both, Skip or Cancel (with Apply to all)
• Copies report bytes and speed with a cancel button; every finished operation shows a summary toast
• Delete or ⌘⌫ moves to the Trash; ⌘Z undoes

This Mac

The first sidebar row (This PC on Windows, Computer on Linux) lists every drive as a card with a used / free bar and “42 GB free of 245 GB”. Click a card to open the drive. ⌘↑ from a drive’s root comes back here. The bar turns red above 90% full. Pasting, new folders and drops are off on this page because it is not a real folder. On Windows the cards show no size yet.

Pinning folders

Right-click a folder → Pin to Sidebar, or drag a folder onto the sidebar (a dashed “Pin here” slot appears). Drag pinned rows to reorder them.

Context menu

Open · Open in Terminal · Open in VS Code · Reveal in Finder · Copy · Cut · Copy Path · Rename · Pin to Sidebar · Move to Trash

What mairok remembers

Icon size, view (grid / list), the preview toggle, pins and sort order persist between launches. Scroll position is remembered per folder. Pick Light / Dark / System from the half-circle toolbar button.

On macOS the settings live in ~/Library/Application Support/mairok/.
