FolderPlus
Supercharge macOS Quick Look with instant folder previews.
What it does
Displays Finder-style tree views and nested folder hierarchies directly inside Quick Look previews. Browses compressed archives like ZIP, TAR, 7Z, and RAR without extracting them first. Provides gallery views, file thumbnails, and dashboard metrics highlighting folder statistics and large files. Filters files instantly as you type using custom parameters like name, size, date, or extension.
Why it works
Native macOS design ensures deep integration with standard Finder behaviors and keyboard shortcuts. Zero data collection and complete offline functionality protect user file privacy entirely. Eliminates repetitive clicking and file extraction steps to speed up asset auditing. Lightweight architecture maintains lightning-fast performance even on massive project directories.
