Paragon Partition Manager 10 Professional can use a "virtual mode" where operations are not actually performed immediately. This is the default, and it is a great way to catch mistakes before they are made.
The application can also use Windows' Volume Shadow Copy (VSS) to take "snapshots" of data. This is a critical feature if you have certain applications running in the background while operations are being performed.
This is another example of the UI, this time for a partition resize operation. As you can see, it provides you with all of the information you need to make the right decision, while being clear and easy to understand at the same time.
