What would this program do that professional recovery tools don't? And to answer the actual question: you'd need low-level file system access that would only be available by using JNI; are you prepared to get into that? (And, of course, you need expert knowledge about whatever file systems this tool should work with - something very few people have.)

If you want to have your problem solved, then you should do it in the standard way for a forum: Describe your problem in detail. Asking people to write a whole complicated program and post it for you, while not providing any specifications as to what this program should do, is just not a reasonable thing to do on any forum. Have a look at our forum FAQ entries NotACodeMill and DoYourOwnHomework and TellTheDetails should help you in asking your question.

What Paul said still applies. Which file systems are you targeting? There's a whole bunch of different ones supported by current operating systems: https://en.wikipedia.org/wiki/Comparison_of_file_systems.

and i want know about this also how to find installed software list from system.


We try to keep topics to single subjects; please start a new topic for this question.

I don't think you appreciate what a "file system" is in computer science terms. Going by your mention of "registry" elsewhere I'm assuming that you will be targeting Windows - before you know the differences between FAT and NTFS by heart you're not in a position to even know the difficulties of what you're asking about. (And, I might add, probably not for a long time after that, either.)
