Sandbox - Exclusions
Manage these settings at: Menu ▸ Settings (gear icon) ▸ Tools ▸ Sandbox ▸ Customize ▸ Exclusions
Specify files or applications that are never virtualized. For example, you can exclude your Downloads folder to ensure that files downloaded while running a browser in the Sandbox are not deleted when you close the browser.
You can enter the file path or click browse to select the location to be excluded. To remove a file path from the list of exclusions click delete.
