And while I’m sure you’re not guilty of any CSI type crimes (or are you?), I’m sure you want to figure out how to permanently delete your files and keep your private things private — after all everyone has to have some secrets! Why emptying your recycling bin doesn’t permanently delete your files When you tell your computer to empty it is recycling bin, your operating scheme only deletes the records it has of the files you want to delete. Yet the files still stay on the hard drive memory. Here’s an analogy: If you think of your files as books in a library and you determine you no longer have use for a sure book. Emptying the trash is equivalent to removing the entry in the library’s card catalog. The book is still there but not without apparent effort found by daily visitors. But if an individual actually wanted to find it, and had a clue where to look, they rather perhaps do so since it is still physically there.

Delete your files, empty your recycle bin, and run Disk Defragmenter located in the Start menu beneath Accessories/System Tools. What this will do is optimize your hard drive by rearranging (most) of your files, and in doing so will most likely overwrite the files you want permanently deleted. Nice! Do it right and do it better While performing a defragmentation will probably do the trick, it’s actually not a viable solution. Waiting for disk defragmentation is not something I’d do each time I wanted to do a permanent deletion. The defragmentation routine is way too long.

You’re in luck too because most Windows operating systems have a command line tool called CIPHER to do the trick! Here’s how to use CIPHER: 1. After closing all windows, open up a command window. 2. Type the following: cipher /w:�driveletter:�foldername where driveletter and foldername correspond to the drive a emplacement of where your deleted file employed to live. 3. Sit back and get enjoyment from your freedom and privacy while your file is genuinely permanently deleted! Here’s an example: I have a picture I want permanently deleted which stored on my computer at the following location: C:�images�scandalous_picture.jpg After deleting this picture and emptying the recycle bin, I would type the following (in a command prompt) to ascertain that I may still run for senator (as long as they don’t catch me in the airport bathroom): C:>cipher /w:C:�images I may then move on to my life of privacy and carefree surfing! You may do better! Although I’m comfortable working with the command prompt, you may not be.
