Q: "...I did not mount the drive, nor did I turn protection on, but somehow thought that the space allocation would be dynamic rather than static."
ANS: The Virtual Partition is created with a set size and should not be confused with the cache. The VP is a convenience and is similar to other types of virtual storage volumes. The cache on the other hand is part of the System Protection.
When using the disk cache you have a trade off: ability to commit changes to disk, but static space to ensure the highest reliability for saving data. The memory cache does not allow changes, but has a dynamic cache. The memory cache is capable of allowing change commits but there is an unacceptable risk for damage when saving very large files or a large number of concurrent files.
We looked at this during the early testing and also thought about the inherent risk when there is a possibility to commit changes to the real system. For these reasons we decided on a dichotomy to allow flexibility when it is required and tighter control when it is not.
Q: "OK, now I am thoroughly confused! I thought that System Protection was accomplished by placing all entries into the Virtual Partition????"
ANS: I hope the explanation above has helped to clarify this a bit better.
Q: "Can I create a Virtual Drive on a removable USB drive or flash drive and move it from computer to computer (each with Returnil installed?) Of course, I would have to save the file changes if I wanted to keep them and the removable drive letter would probably need to be the same on all PCs."
ANS: This is not available in 2.0. For now, the VP is created on the System Partition in the RVS root folder. After it is created though, you can move it to a USB with enough space. Further you can move the file to another computer but you will need RVS on the other system to mount the file.
In the next series, you will be able to create your VP on alternate partitions or disks during installation and using the repair feature in the uninstaller.
