Use Windows Built-in File Shredder
Windows do provide you access to a simple and easy-to-use option for permanently deleting a file. This method can be pretty easy to shred the files without the possibility of any recovery. The built-in secure data deletion tool that forms part of the Windows system is called Cipher. The method or the option has continued to exist since the days of Microsoft XP. If you are not happy with using any third-party options for secure deletion of your files, using the built method may prove to be quite handy.
The method does not come with a graphical interface, making it more challenging to use if you are a newbie.
Before you can use the option to shred the files, you need to delete the files you want to shred. You should first delete the files and then clear your recycle bin. The Cipher command only works with the files that have already been deleted.
Once you have deleted the files that you want to erase securely and cleared the recycling bin, the next step should be to follow the steps here below –
- Launch Powershell on your computer.
- Make sure that you are running it as an administrator.
- Type in the following command: cipher /w:C:
That does it. The command will securely wile all the deleted files from the target drive like C: or D:, which has unallocated space or data. That would mean the command will not touch any files that have not been deleted. It will shred only those files that have been deleted, as explained in the above example.
The process can take a very long time, depending on how much data you have deleted over time. If you want to speed up the task, you can specify the exact folder you wish to operate the cipher command.
A few of the examples would include:
Cipher /w:C:\Users\Jim\Documents would handle only those files deleted from the Documents folder for the specified user.
