Folder Preview Pro — Mac download

Dual Columns view changes how you scan nested folders without opening them.

Quick Look for folders — Press Space or Command-Y on any folder to see its contents instantly.

Archive browsing — ZIP, TAR, GZ, 7Z, and RAR files preview the same way, no extraction needed.

Dual Columns — Two side-by-side panels let you compare folders or navigate parent and child directories at once.

Contents menu — Right-click a folder in the preview and choose Contents to drill down level by level without leaving the panel.

Drag-out support — Files can be dragged straight from the list or icon preview to a Finder window or another app.

Column control — Right-click any column header to show or hide details, keeping the view clean for the task at hand.

Quick Look needs to be switched on before Folder Preview Pro can do anything. Open System Settings, go to the Quick Look section, and make sure the extension is enabled. The app will prompt for this on first launch, but it is easy to miss if you click through quickly.

Prevent macOS stalling on large collections by raising the archive scan limit

• Archive size limit — Default scanning is fine for small files, but for large collections set the limit to 5 GB or 10 GB. It stops macOS from stalling while the preview calculates every nested item.
• Column layout — Right-click any header in the preview and switch off columns you rarely need, like date modified or file size. A leaner column set makes scanning faster.
• Default view — Decide between icon and list view before heavy use. Icon view suits folders full of images or design assets; list view suits archives and document folders.
• Dual Columns toggle — Keep it off for everyday browsing, and turn it on when you compare two folders or move files between a parent and a child directory.

Bypass opening every file manually in a chaotic project folder

You are in Finder, sorting a project folder that has grown out of control. There are client files, exported PDFs, a few old ZIP archives, and a folder called Final_v3 that you do not trust. Instead of opening each one, you select the first folder and press Space. The contents appear in a Quick Look panel: a clean list of filenames, sizes, and dates.

You press the Down arrow to move to the next item. A RAR archive from last month shows its internal structure without extraction. You spot a duplicate set of invoices, right-click the folder inside the preview, and choose Contents. The panel drills one level deeper. You drag two PDFs out of the icon view onto the Desktop before closing the panel.

Then you compare Final_v2 and Final_v3 in Dual Columns view. The difference is obvious in ten seconds: one extra folder and a missing cover image. You copy the missing file across and close the preview. The whole check takes under a minute.

Compare mirrored directories without opening a second Finder window

The most visible update is Dual Columns view. It removed the need to open two Finder windows side by side just to compare folder contents. For anyone who juggles mirrored project directories, this alone changes the habit: press Space, compare, close.

The Contents item in the context menu made archive and nested-folder browsing more direct. Instead of opening a folder to preview its child, you right-click and step down one level inside the same panel. That cut down on repeated Quick Look calls.

Drag-and-drop out of the preview was a small change that feels larger in daily use. Before, you had to close the preview, open the folder, then drag what you needed. Now the preview works as a temporary source window. Files go straight to Finder, an email draft, or a chat window.

Archive size options of 5 GB and 10 GB matter for teams that work with media bundles or database dumps. The old ceiling was too low for those cases, so the extension would either refuse the preview or take long enough that people gave up. The 3.1 limit options made folder preview pro useful on bigger archives without losing responsiveness.

Finally, moving folder size information from the status bar to the toolbar under the folder name tightened the layout. The number now sits closer to the folder title, where your eye goes first.
