I don't quite understand what I am gaining with this functionality. I know that it can only be established when creating a new pool, and accorinding to the built-in description, will redirect non-persistent files to a disposable disk that is deleted at the end of the user session. Is this an altnerative to refreshing the desktop immediately following the end of the session? Further, you can specifcy a size for this file... what happesn when you exceed the capacity. i have not been able to find out much information in the interwebs. Perhaps more conflicting information about this feature.
