If you think that pressing shift +delete erases your data permanently then you need to think again.When you delete files from your PC, anyone can recover it using recovery software.,There are plenty of free recovery softwares available like   pc inspector file recovery ,pandora recovery,recura..etc.but then what exactly does “permanent deletion of a data mean“?

When you delete your file data is not deleted from hard disk instead  the space on the disk that was occupied by the deleted data is deallocated and the space is available for use when new data is written to the disk. the data can be recovered by recover softwares  until new data is written onto the deallocated space.

I have come up with two methods to delete data permanently without using third party softwares .

1.The labourus method: Delete the files , and from recycle bin  and run Disk Defragmenter located in the Start menu under Accessories/System Tools. What happens is that it optimize your hard drive by rearranging (most) of your files, and in doing so it will most likely overwrite the files you want permanently deleted.

2. Cipher.exe : Admin can use Cipher.exe to encrypt and decrypt data on drives that use the NTFS file system and to view the encryption status of files and folders from a command prompt. here’s how to use the command :

After closing all windows, run command prompt as admin .Type cipher /w:driveletter:\foldername , and then press ENTER. Mention  the drive and the folder that identifies the volume that contains the deleted data that you want to overwrite. Data that is not allocated to files or folders will be overwritten.

and wait for few minutes for it to get deleted ..permanently

the only thing against this method is that it can takes a long time for data to delete

NOTE: the data once deleted using  cipher is irrecoverable .
