How to save data while the protection is on?

Returnil Virtual System can only protect the system partition.
 
 
For example, if you have two partitions "c:\ d:\" and the Windows is set up in "c:\" drive. The Reurnil will only protect the "c:\"  drive. You can save your data in "d:\"  drive freely and the data changed in "d:\" drive will NOT be lost after you restart your computer.
 
If you have only one partition, you can create a new partition with special tools such as PartitionMagic. With Returnil, you can also create a virtual partition and save your data in this partition freely.
