QuickLook Enhances File Previews in Windows 11

22 Feb 2026

QuickLook, an open-source application, now offers Windows 11 users the ability to preview files using the spacebar, a feature long appreciated by MacBook users. This app integrates seamlessly into File Explorer, allowing users to view images, videos, PDFs, and common document formats in a lightweight pop-up.

Features and Installation

QuickLook supports zooming images, video playback, and volume control. Users can also open files in their default applications directly from the preview. The app runs quietly in the background, ensuring a smooth user experience.

To install QuickLook, users can visit the Microsoft Store, search for the app, and click 'Get' followed by 'Open'. A prompt will confirm that the app is running in the background. In File Explorer, users can select a file and press the spacebar to preview it.

Limitations and Compatibility

While QuickLook enhances file browsing, it can be resource-intensive on older or low-powered machines, consuming notable CPU and memory. It does not support certain file formats such as .avi and .wmv, and is incompatible with Windows 10/11 in S mode.

Despite these limitations, QuickLook remains a simple and unobtrusive tool that significantly improves file browsing for users with compatible systems.
