Sandbox - Virtualized processes

Manage these settings at: Menu ▸ Settings (gear icon) ▸ Tools ▸ Sandbox ▸ Customize ▸ Virtualized processes

Specify files that are always virtualized when they are run. Click browse and select the file or path to be run inside the Sandbox. To remove a file or path from the list click delete.

You can also add entire folders so that every application in the folder is virtualized.
