CTOnews.com, October 27, according to foreign science and technology media pureinfotech reports, users can use Cipher commands in Win10, Win11 systems, without formatting, erase deleted data so that it can not be recovered.

CTOnews.com Note: Cipher.exe is a command-line tool (included in Windows 2000) that can be used to manage data encrypted through the use of encrypted File system (EFS).

Image source: pureinfotech Microsoft subsequently upgraded its Cipher.exe tool to develop the ability to permanently overwrite (or "erase") all deleted data on the hard drive.

After the user deletes the file or folder, the system will not delete the complete data from the hardware, but just mark it before it is overwritten by other data, and then it can be restored in various ways.

Say the important thing three times:

The operation is risky, please make sure to make a good data backup before the operation.

The operation is risky, please make sure to make a good data backup before the operation.

The operation to delete the contents of the file is as follows:

1. Open the start button in Win10, Win11 system

two。 Search for a command prompt, and then right-click run as administrator.

3. Enter the following command to safely erase deleted data

Cipher / w:DRIVE-LETTER:\ FOLDER-PATH\ in the command, replace "DRIVE-LETTER" with the drive letter that contains the deleted content, and replace "FOLDER-PATH" with the path of the folder to be completely deleted from the hard drive.

Image source: pureinfotech for example, this command uses Cipher to erase the "aws-rclone-test" folder I deleted earlier: cipher / waws-rclone-test c:\ aws-rclone-test.

4. Safely erase the free space that may contain deleted data information by typing the following command, and then press enter:

Cipher / w:DRIVE-LETTER:\ in the command, replace "DRIVE-LETTER" with the drive letter of the storage for which you want to erase the free space. For example, this command erases only the free space in "C:\" that may contain recoverable data: cipher / wpurc:\.

5. (optional) Type the following command to overwrite the deleted data multiple times, and then press enter:

Cipher / w:DRIVE-LETTER:\ / p3 in the command, replace "DRIVE-LETTER" with the drive letter of the storage for which you want to erase free space. You can also change "3" to the number of passes you want to use. The higher the number, the longer it takes to complete the process.

After completing these steps, Cipher will overwrite the deleted data, making it difficult for anyone to use the recovery software to rebuild and recover files and folders from the hard drive.
