sandbox settings confusing and vague - Run a Program in the Sandbox

This link is not helpful at all >:(
Link: Comodo Help

Partially Limited

This doesn’t tell me anything about which setting is the most secure.
The settings should be renamed !

Using a level 1 to 4, level 1 being most secure how would you categorize the sandbox settings ?

Can somebody explain what the difference between the settings. The help link isn’t helping just making it worse

The help file I think explains it pretty well, but if you want the choices numbered by which is most restrictive:

1 - Untrusted
2 - Restricted
3 - Limited
4 - Partially Limited

Thank you for making it clear for me.

The higher level of restriction the more probable that the sandboxed program won’t work.
