# QuickLook
[](https://ci.appveyor.com/project/xupefei/quicklook)
*This project is currently under heavy development. Come back often to see what's new.*
## Background
[Quick Look](https://en.wikipedia.org/wiki/Quick_Look) is among the few features I missed from Mac OS X. It enables *very* quick preview of file by pressing Space key while highlighting it, without opening its associated application. Then I decide to add this feature to Windows by myself, which results this “QuickLook” project.
You may ask, why you write this when there several alternatives available on the Internet (e.g. [WinQuickLook](https://github.com/shibayan/WinQuickLook) and [Seer](https://github.com/ccseer/Seer))? The answer is that, they are all among those which no longer actively developed, lack of support of file types and plugins, or asking user for amounts of $$$.
## Features
Till now, QuickLook supports the preview of
- Images: e.g. `.png`, `.jpg`, `.bmp` and `.gif`
- Compressed archives: `.zip`, `.rar`, `.7z` etc.
- Pdf file
- All kinds of text files (determined by file content)
- Microsoft Word (`.doc`, `.docx`), Excel (`.xls`, `.xlsx`) and PowerPoint (`.ppt`, `.pptx`) files (requires MS Office installation)
- Video files (`.mp4`, `.mkv`, `.m2ts` etc.)
- HTML files (`.htm`, `.html`)
- Markdown file (`.md`)
- Other files and folders will be shown in a information box
## Usages
In-place preview / Integrate with 3rd-party file manager
- You may set up a custom hot key that fires event `QuickLook.exe C:\path\to\your\file.txt`. Press your hotkey for the 2nd time will close the existing preview window.
Hotkeys in preview window:
- Space Show/Hide the preview window
- Ctrl+Wheel Zoom in/out
## Development
The previewing ability can be extended by new plugins. Read the [plugin interface](https://github.com/xupefei/QuickLook/blob/master/QuickLook/Plugin/IViewer.cs), [context object](https://github.com/xupefei/QuickLook/blob/master/QuickLook/Plugin/ContextObject.cs) for more information. [Pre-shipped plugins](https://github.com/xupefei/QuickLook/tree/master/QuickLook.Plugin) contains more detailed implementation.
Note that any plugin must be under the `QuickLook.Plugin` namespace, has the filename similar to `QuickLook.Plugin.YourPlugin.dll` and placed under `\Plugins\QuickLook.Plugin.YourPlugin\` subfolder.
