Little tips and tricks for this morning is how to clean you hard-drive. For whatever reason.
For so many years, most majority of computer-users believe (fervently) that deleting a file from Recycle Bin in Windows (or pretty much any other Operating Systems I know) will forever obliterate that data to the furthest edge of the universe and beyond.
Until I showed them how easy it is to retrieve it under 5 minutes.
In a nutshell, the fact is when you delete a file in Windows, it only deletes the pointer of that file. But it leaves the actual data intact – until that exact space is either re-utilized or cleared. To fully understand that, you need to know the basic idea how file works. When you save a file in your drive, it creates a header/pointer where it stores all the information of that file – including where and how big that data of that file is being stored. When you delete a file, the system would simply either rewrite the header to say that the area where the data resided is now empty and free for the taking of any new files, or, delete the header completely. Neither, actually deletes the data. Thus, when you do feel the send a file into oblivion, there are extra steps you must follow and understand.
