    When you delete a file, even by Shift + del, the file does not physically get deleted from the hard disk. All that gets deleted is the path to the physical location of the file.

    In order to restore this file, a file recovery software is needed. These software look for files that exist on the hard disk but are not referred to by the OS (I think, not sure though).

    Even after you've formated your hard disk you can recover your files. However, this may not be possible if you've used low level formatting.

    Please correct me if I'm wrong.

    Ya you are right whenever we delete a file the os removes the refering pointer or flag to the file and makes the space available to be used by another file

    But if we restore the deleted file before the space is filled up by some other data then, we can again make windows set the flag to 1 which means you have recovered your file

    That is why when you click restore the file again is available at the same location where it was previously.

    Please correct if I'm wrong.

    Ya we can set recovery point by using backup & restore application & restore to certain dates. but it doesn't restore your data, its restores the software installed & other os setings. You can take backup to an external drive that will save your data.

    TO create a System Restore point?

    Click Start, All Programs, Accessories, System Tools, System Restore

    For Classic Start Menu: Click Start, Programs, Accessories, System Tools, System Restore.

    Click Create a restore point, and then click Next.

    In the Restore point description box, type a name to identify this restore point. System Restore automatically adds to this name the date and time that this Restore Point is created.

    To finish creating this restore point, click Create.

    You can also launch System Restore window by typing the command below, in the RUN box:

    %SystemRoot%\System32\restore\rstrui.exe
