PGP virtual disk question
I have two questions about pgp virtual disk
1. When a virtual drive is created and given a drive letter, a .pgd file is created. Am I correct in assuming that the physical drive that the actual files reside on (when the virtual drive is opened up), (even though is might be a virtual partion of a physical drive) is the drive that the .pgd file is on. What I am really asking is, is a new pgp virtual drive created on that physical drive when the .pgd file is opened up and then "uncreated" when the pgp virtual drive is closed. Therefore there could be one or more pgp virtual drives on a virtual drive partition. Multiple virtual drives on a virtual drive. Is this a correct interpetation on how it works.
2. It seems obvious (but I want to be sure) that the size of the drive must be suffucient to contain the .pgd file. The size of the .pgd file is the size of pgp virtual drive when open up. If this is not true then what is the ratio of the physical or virtual disk partition that must be allocated for a given size .pgd file.
