Split panes and tabs

Every folder,
side by side

Split the window into up to four panes, as a 2×2 grid. Drag between them or copy across with F5. Keep a tab for each task, save the whole layout as a workspace, and compare or sync two folders when they drift apart.

  • Split panes

    Split Right and Split Down add panes, up to four. Tab moves between them.

    Read the guide
  • Tabs and workspaces

    Drag tabs into the order you like; they come back when Burrow opens. Save a layout as a workspace.

    Read the guide
  • Copy, move and the shelf

    ⌥⌘V moves, Copy to… takes a typed destination, and the shelf holds files while you browse.

    Read the guide
  • Compare two files

    Text as a diff; pictures side by side, under a slider, or with changed pixels in red.

    Read the guide
  • Compare and sync folders

    What's only on each side and what changed, then sync either way with one undo.

    Read the guide
  • A sidebar you arrange

    Add, rename and reorder favorites, make groups, and drag any section to where you want it.

How it works

Open a folder where you want it

Drag a folder to the edge of a pane and drop it in the highlighted zone, and it opens there. The divider drags to resize, and Toggle Split goes back to one pane.

Moving files without worry

Name clashes ask once: replace, keep both or skip. Every copy and move undoes with ⌘Z, and the shelf lets you gather files from several folders before copying them in one go.

Two folders, made to match

Sync copies what's missing either way, syncs both ways with the newer file winning, or makes one side match the other. It says what it will do before it does it.
