# Setting an Application to Open When You Insert a CD/DVD

You can set the Windows application of your choice to open when you insert a music CD, picture CD, video DVD, or a blank CD or DVD.

1. From the macOS Finder, choose **Apple menu** > **System Preferences**.
2. Click **CDs & DVDs**.
3. From the disc type menu of your choice, choose **Open other application**.
4. Choose a Windows application from `/username/Applications (Parallels)/Windows Applications`.

When you insert a disc of the type you selected, the Windows application you chose automatically opens.

**Note:** 1. If you're unable to set a Windows application to open when you insert a CD or DVD, be sure that [sharing macOS applications](https://docs.parallels.com/landing/pdfm-ug/v20-en-us/parallels-desktop-for-mac-20-users-guide/use-windows-on-your-mac/setting-how-windows-works-with-macos/sharing-items-between-macos-and-windows/sharing-applications) is enabled and that macOS CD/DVD-ROM is not selected in CD/DVD Preferences.\
2\. To enable a Windows application to open when you insert a CD or DVD, Parallels Tools must be installed. In most cases, Parallels Tools are installed by default.
