QuickLook is a free app for Windows that offers instant previews of various file types, including images, media files, documents, and archives. Using the spacebar while viewing any file instantly displays its contents. The feature allows users to quickly jump between files using the arrow keys. Although not all file formats supported by QuickLook are available on Mac's Quick Look, this app is more versatile than its Mac counterpart. Users can install plugins to add support for additional file types, including Microsoft Office files and EPUB ebooks. This app provides a similar functionality to Apple's Quick Look feature, which is widely praised for its usefulness.
