Whenever you delete a file from your system, only the address to the file is deleted from NTFS and FAT drives. These files remain hidden on your system unless overwritten by other files. Hence using any data recovery tool, it is then possible to recover these “deleted” files in a jiff. This poses a grave risk of data theft; hence some caution is advised when handling such sensitive data. Data such as net banking passwords, private photos, private photos, credit card details, videos, emails, and chat messages are classified as sensitive. Therefore, it becomes more important to wipe your disk clean when you decide to sell or give away your PC.

We will discuss various ways to overwrite your confidential data effectively. Following are some of the prominent ways to effectively encrypt/ scramble your confidential files beyond repair:

Method #1 Using Windows PowerShell and Cipher

This method takes advantage of the inbuilt Windows feature that can be used to overwrite the deleted files.

  1. Launch Windows PowerShell by searching for it.
  2. In the command prompt enter: cipher /w:<filepath> as shown below in the snippet.
  3. The tool will now attempt to overwrite all the deallocated data in the filepath
  4. Note: your existing data in the file location will remain intact, and only the deleted files will be overwritten.

    Note: The process to overwrite the deleted files will take some time. So, be patient.

Method #2 Changing the Recycle Bin’s Properties

When you delete a file on your system, it gets dumped into the Recycle Bin, and from there, one can quickly restore files to their previous locations.
