I've deleted some files on my machine. Can your software help me to restore them?

The only way to see if it can help you is to run the demo version of the software and see if it can find the files. If the demo can not find them, the commercial version also would not be able to find them. If the demo can find them, the commercial version may be able to restore them, as long as the files have not been overwritten by other files (temp OS files, etc).
