# Recent Documents (Windows & macOS)
## Overview
Windows and macOS provide access to a list of recent documents opened by
the application via JumpList or dock menu, respectively.
__JumpList:__
![JumpList Recent Files][jumplist-image]
__Application dock menu:__
![macOS Dock Menu][dock-menu-image]
To add a file to recent documents, you need to use the
[app.addRecentDocument][addrecentdocument] API.
## Example
### Add an item to recent documents
Starting with a working application from the
[Quick Start Guide](quick-start.md), add the following lines to the
`main.js` file:
```javascript fiddle='docs/fiddles/features/recent-documents'
const { app } = require('electron')
app.addRecentDocument('/Users/USERNAME/Desktop/work.type')
```
After launching the Electron application, right click the application icon.
You should see the item you just added. In this guide, the item is a Markdown
file located in the root of the project:
![Recent document](../images/recent-documents.png)
### Clear the list of recent documents
To clear the list of recent documents, you need to use
[app.clearRecentDocuments][clearrecentdocuments] API in the `main.js` file:
```javascript
const { app } = require('electron')
app.clearRecentDocuments()
```
## Additional information
### Windows Notes
To use this feature on Windows, your application has to be registered as
a handler of the file type of the document, otherwise the file won't appear
in JumpList even after you have added it. You can find everything
on registering your application in [Application Registration][app-registration].
When a user clicks a file from the JumpList, a new instance of your application
will be started with the path of the file added as a command line argument.
### macOS Notes
#### Add the Recent Documents list to the application menu
You can add menu items to access and clear recent documents by adding the
following code snippet to your menu template:
```json
{
"submenu":[
{
"label":"Open Recent",
"role":"recentdocuments",
"submenu":[
{
"label":"Clear Recent",
"role":"clearrecentdocuments"
}
]
}
]
}
```

When a file is requested from the recent documents menu, the `open-file` event
of `app` module will be emitted for it.
