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.
