How to Open Two Folders Side by Side in macOS's Finder

Updated August 18, 2026

Moving files between two folders is easiest when you can see both at once — which is why it’s odd that Finder, decades in, still can’t split a window in two. What macOS gives you instead is window management: two Finder windows, arranged next to each other. Here’s every way to do that, fastest first, and then the way that doesn’t need redoing every time.

Two windows, snapped into halves#

On macOS Sequoia (15) and later, window tiling is built in:

  1. In Finder, press N (or File → New Finder Window) so you have two windows.
  2. Drag one window to the left edge of the screen until a translucent outline appears, then release — it fills the left half.
  3. Drag the other window to the right edge.

Prefer clicks to dragging? Hover over the green button in a window’s top-left corner and pick a half from the tiling menu, or use Window → Move & Resize. Unlike full-screen Split View, tiled windows are still ordinary windows — your menu bar, Dock, and other apps stay put.

Split View, if your Mac is older#

Through macOS Sonoma, side-by-side means full-screen Split View:

  1. Click and hold the green button on the first Finder window.
  2. Choose Tile Window to Left of Screen. The window fills the left half and macOS shows your other windows as thumbnails.
  3. Click the second Finder window to fill the right half.

You can drag the center divider to rebalance, and drag files across it freely. The catch: Split View is a full-screen Space of its own — the menu bar hides, your other windows vanish, and getting out means moving the pointer to the top of the screen and clicking the green button again. Fine for one long copy session; heavy for “let me just check two folders.”

If you want real Windows-style snapping on an older macOS, the free Rectangle (or paid Magnet) adds drag-to-edge tiling on any version.

Tabs — and the drag trick that almost saves them#

T opens a second folder as a tab, which is _not_ side by side — only one folder is visible at a time. But two tricks make tabs more useful than they look:
  • Drag files onto another tab’s title and pause — the tab springs open so you can drop inside it. Or just drop directly onto the tab title itself.
  • Window → Merge All Windows gathers a screenful of scattered Finder windows into one tabbed window.

Good to know, but it doesn’t answer the actual question: you still can’t see both folders at once.

The dual-pane answer#

Notice what every method above has in common: it’s window arranging, and it’s on you every single time. Open a second window, drag it into place, snap it — and when the windows close, the arrangement evaporates. Finder has no concept of two folders sharing one window, so there’s nothing for it to remember.

File managers built around dual panes solve this at the root: one window, two folders visible, each pane with its own tabs and history, files dragged — or keyboard-moved — straight across. It’s a layout with a long pedigree (Norton Commander was doing it in the ’80s), and several Mac apps offer it today — we compared the best Finder alternatives, free options included.

FAQ#

Can Finder show two folders in one window?#

No. Tabs (T) hold multiple folders but display one at a time, and column view shows a single path’s hierarchy — parent, folder, child — not two arbitrary folders. Seeing two folders at once means two windows, or a dual-pane file manager.

How do I move files between the folders once they’re side by side?#

Drag them — on the same drive that moves; across drives it copies (hold while dropping to force a move). By keyboard: C then V moves files, which is its own hidden trick — here’s the full story.

Does macOS have window snapping like Windows?#

As of macOS Sequoia (15), yes: drag a window to a screen edge, or use Window → Move & Resize. On Sonoma and earlier there’s only full-screen Split View — or a free utility like Rectangle.
