A modern file manager that helps users organize their files and folders.

Quick Overview

QuickLook is an open-source file previewer for Windows, similar to the Quick Look feature on macOS. It allows users to quickly preview various file types by pressing the spacebar while selecting a file in File Explorer, providing a fast and convenient way to view file contents without opening them fully.

Pros

  • Supports a wide range of file formats, including images, videos, text files, PDFs, and more
  • Lightweight and fast, with minimal impact on system resources
  • Customizable through plugins, allowing users to add support for additional file types
  • Integrates seamlessly with Windows File Explorer

Cons

  • May occasionally encounter compatibility issues with certain file types or Windows versions
  • Some advanced features may require additional plugins or configuration
  • Not as deeply integrated into the operating system as the macOS counterpart
  • Limited customization options for the default user interface

Getting Started

To get started with QuickLook:

  1. Download the latest release from the GitHub releases page.
  2. Run the installer and follow the on-screen instructions.
  3. Once installed, select a file in File Explorer and press the spacebar to preview it.
  4. To close the preview, press the spacebar again or hit the Esc key.

Code Comparison

Files (C#):

public static async Task<StorageFolder> GetFolderFromPathAsync(string path)
{
    if (string.IsNullOrEmpty(path))
        return null;
    try
    {
        return await StorageFolder.GetFolderFromPathAsync(path);
    }
    catch (Exception)
    {
        return null;
    }
}

QuickLook (C#):

public static string GetFileDescription(string path)
{
    var info = new FileInfo(path);
    return $"{info.Name} ({info.Length} bytes)";
}

The code snippets demonstrate different approaches:

  • Files focuses on asynchronous operations and exception handling for folder access
  • QuickLook emphasizes simplicity in file information retrieval

Background

One of the few features I missed from macOS is Quick Look. It allows users to peek into a file content in lightning speed by just pressing the Space key. Windows, on the other hand, does not have this handy feature ... until now!

I am aware that several alternatives are already available on the Internet (e.g. WinQuickLook and Seer). Despite these options, I still decided to craft another one by myself, because they are either not being actively developed, lack of variety, or ask for some :dollar:.

Highlights

  • Tons of supported file types (full list here)
  • Fluent design
  • Touchscreen friendly
  • HiDPI support
  • Preview from Open and Save File Dialog
  • Preview from 3rd-party file managers (see a list here)
  • Easily extended by plugins
  • Strict GPL license to keep it free forever

Usage

Download/Installation

Get it from one of the following sources:

  • Microsoft Store (Windows 10 users only, no preview in open/save-dialogs available) Store Link
  • Installer or portable archive of the stable version from GitHub Release
  • Using Scoop: scoop install quicklook
  • Nightly builds from AppVeyor and GitHub Action

What are the differences between .msi, .zip, Nightly and Store versions?

Note: Don't forget to check out the plugins for previewing office-files, epubs, fonts and more!

Typical usecase

  1. Run QuickLook.exe (only necessary if autostart is disabled)
  2. Select any file or folder (on the Desktop, in a File Explorer window, in an Open or Save-File dialogue, doesn't matter)
  3. Press Spacebar
  4. Enjoy the preview and interact with it
  5. Preview next file by clicking on it or using arrow-keys (arrow-keys move selection in the background if the preview window is not in focus)
  6. When you're done close it by either hitting Spacebar again, pressing Esc or clicking the ⨉ button

Hotkeys and buttons

  • Spacebar Show/Hide the preview window
  • Esc Hide the preview window
  • Enter Open/Execute current file
  • Mouse ↑ ↓ ← → Preview another file
  • Mouse Wheel Zoom in/out (images)
  • Ctrl+Mouse Wheel Zoom in/out (PDFs)
  • Wheel Increase/decrease volume

Supported file types, file manager integration, etc.
