The file explorer in Windows is quite powerful, and in versions like Windows 10 it has a built-in preview side panel that works mostly with images and not much else.
The ability to press a key and power preview a Word document, spreadsheet, PDF, compressed file, or simple GIF, it is not something that exists within Windows by default, not without having to open another application and leave the explorer. But with a tool like QuickLook you solve that deficiency in a few seconds.
QuickLook is an application free and open source which is currently in constant development and receiving news. In a fairly simple project that seeks to bring one of those functions that macOS has always had and that many miss in Windows: the preview of all types of files in the explorer.
Unlike other similar projects like Seer, which we have talked about before in Genbeta, QuickLook is completely free and does not limit its updates to paid users.
The current version is 0.1.10 and it was released just 2 days ago. You may download the installer or source code from the releases channel on GitHub. Once installed on your computer, you just have to run the program for the first time and check that it is running in the background in the Windows taskbar indicators.
To activate the preview on a file you just have to press the space bar. You can use the keyboard arrows to navigate to the next or previous file, and you can use the CTRL key + the mouse wheel to zoom.
QuickLook supports image files such as .png, .jpg, .bmp, and .gif. Compressed files such as .zip, .rar, .7z. Text files, and PDF files. Office documents such as .doc, .docx, .xls, .xlsx, .ppt, and .pptx. Video files such as .mp4, .mkv, .m2ts. HTML and HTML files, and MarkDown files.
