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:
- Download the latest release from the GitHub releases page.
- Run the installer and follow the on-screen instructions.
- Once installed, select a file in File Explorer and press the spacebar to preview it.
- 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

QuickLook
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 but I still decided to craft another one by myself, because they are either not being actively developed, lack of variety.
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 and later only). Not supported on Windows 10 S. Not support file preview in Open-File or Save-File dialogs.

- Installer or portable archive of the stable version from GitHub Release
- Using Scoop:
scoop bucket add extras && scoop install extras/quicklook - Nightly builds from 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!
