                           Hi Viewers, last few days i am not posting any post because i am very busy with other work. But now this time i am give you instruction about what happen with a file when that file is deleted.
     There are many type of people with different motive to delete a file, some people delete a file to make space, some people are having a sensitive videos of file for that case they are thinking that they should delete the file or video before any family member see this but if unfortunately the father of deleter is know about how to recover a file and the father want to recover deleted family video by mistake the sensitive video is recovered and when the all family member see together.....................
    OK now lets know what is happen with the deleted file which is delete by the boy-------

   When you Delete a file form your computer, actually that file is not removed completely from your computer. The Windows OS user data using two file table first is File Allocation Table (FAT) second is Master File Table (MFT) , in a simple way we can say the FAT or MFT tells the computer where the file begins and ends. Macintosh OS uses the same type of system in this OS we called it Nodes.

 When a file is deleted, Pointers to the file is removed by the OS and in the FAT orMFT the space is mark is available which is authorized by the file. The computer does not delete the actual data that was contained in the file.When the OS removes the pointers to the files, the data remains on the hard drive until the computer over-write the file with different data.

  There are many software to Recover data one is RECUVA lets know about Recuva------

How Recuva works

Windows uses the Master File Table (MFT) as an index to the files it stores on your hard drives. As we mentioned before, when you delete a file, it's faster for Windows to mark its MFT entry as 'deleted' than for Windows to overwrite the file itself, so the file is left on the hard drive.

Regular recovery process
When you first delete a file, Windows does not overwrite the MFT entry until it needs to reuse it.
Recuva scans the MFT for files marked as deleted. Since MFT entries for deleted files are still complete (including when the file was deleted, how big it is, and where it lives on the hard drive), Recuva can give you a comprehensive list of many files and help you to recover them.
As Windows finds the need to create new files, however, it will eventually reuse and overwrite these MFT entries as well as the spaces on the hard drive where the new files actually live. That's why Recuva can't recover every file - and that's why your best bet is to run Recuva as soon as you realize the file's been deleted.

Deep scan process
The deep scan process uses the MFT to look for files, as well as the contents of the drive. Recuva searches every cluster (block) of the drive to find file headers indicating the start of a file. These headers can tell Recuva the file name and its type (for example, that it's a JPG or a DOC file).
As a result, deep scans take a long time. There are thousands of file types and Recuva can identify the most important ones.
If the file is fragmented on the drive, however, Recuva will not be able to piece it back together.

Recuva's two-scan method
Recuva performs two scans whether you use the regular recovery or deep scan process. The first scan analyzes your computer and searches for files that Recuva can recover.  The second scan then analyzes those files to assess the chances of their successful recovery.
If you stop the first scan while it's in progress, Recuva will not display any information about the files.  If you stop the second scan while it's in progress, you will be able to view the files Recuva has found, but the status information will not be as accurate as a full scan would provide.
