Hi, I have used Sandboxie and only recently learned about Returnil. After reading the product description, I would like to know two things. 1) Returnil seems like a sandbox for the entire system that auto-deletes the sandbox upon shutdown of the computer. If this is so, how does one retain information that one would like to keep, e.g., newly created documents, downloaded files, etc? 2) Is sandboxie really necessary as a browser protector if one is using Returnil? What would be the purpose of using them together? I like to keep my system as lean as possible and it seems using them both is overkill. Because I'd ideally just use one of them on my system, your opinions and answers are very welcome. If your comments are persuasive I may use both. I just haven't thought of a reason to as of now. thanks.
