What you get

Everything Quick Look should’ve done.

One lightweight extension that makes folders and archives readable at a glance.

Folder preview

Folders, previewed.

A Finder-style tree right inside Quick Look. Expand nested folders, read names, sizes, kinds and dates, and sort by any column — without ever opening a window.

  • ✓ Expandable, nested tree view
  • ✓ Names, sizes, kinds & modified dates at a glance
  • ✓ Sort by any column, just like Finder
  • ✓ Dashboard view surfaces folder stats & biggest files

Gallery view

Every image, at a glance.

Image-heavy folders switch to a thumbnail gallery automatically. Scrub the size slider, drill into subfolders, and preview any file in the side pane.

  • ✓ Crisp thumbnails for PNG, JPEG, HEIC, GIF, PDF & more
  • ✓ Four thumbnail sizes — S, M, L, XL
  • ✓ Auto-routes for image-heavy folders
  • ✓ Drill-in navigation with breadcrumbs

Archive browser

Browse any archive.

Peek inside ZIP, TAR, 7z and RAR without extracting a single file. Walk nested folders, check sizes and dates, and decide before you unpack.

  • ✓ Look inside ZIP, TAR, 7z, RAR, GZ & more
  • ✓ Browse nested folders within the archive
  • ✓ See file sizes & dates before unpacking
  • ✓ No extraction, no temp clutter

No unzip needed

Peek before you unzip.

Stop extracting archives just to find one file. FolderPlus reads the contents in place — and when an archive is locked, it asks for the password and opens right up.

  • ✓ Opens password-protected archives
  • ✓ Find one file without unpacking the whole thing
  • ✓ Fast even on large archives

Built for macOS

Feels built right in.

Native AppKit and SwiftUI, full keyboard navigation, context menus and customizable columns. It looks and behaves exactly like the Mac you already know.

  • ✓ Native design — no Electron, no web views
  • ✓ Full keyboard navigation & context menus
  • ✓ Universal binary for Apple Silicon & Intel
  • ✓ Lightning-fast, even on huge folders
FolderPlus integrated natively into macOS

Wide format support

If it’s compressed, FolderPlus reads it.

Browse the contents of every common archive format — no extraction, no extra tools.
