How to Secure Your Data with Cipher on Windows 11
The Cipher security tool overwrites deleted data on Windows 11. Using Cipher prevents unauthorized individuals from recovering sensitive information you have erased.
Open Windows Terminal as administrator and run the command cipher /w: followed by your target drive letter. This command overwrites all deleted data on the selected drive, making it unrecoverable.
What Is Cipher and Why Should You Use It?
Cipher is a handy tool built right into Windows that helps protect your files. It can encrypt files to keep them private and also securely wipe deleted data from your hard drive. Using Cipher ensures that information you no longer need is permanently removed and unrecoverable, significantly boosting your privacy.
When files are deleted, the actual data stays on the hard disk until new information overwrites it. When you delete files or folders, the disk space they occupied becomes available for new information. Deleted data remains on your hard drive until new information overwrites it. This data can be recovered using specialized tools like low-level disk editors or data-recovery software, which scan for information in unwritten disk sectors.
The Encrypting File System (EFS) creates a temporary backup of a file before encrypting it. This is a safeguard against data loss should an error occur during encryption. Once encryption finishes, this backup copy is removed.
As with other deleted files, the data isn’t removed until overwritten. Using the Cipher.exe command, you can overwrite the deleted data to prevent unauthorized recovery.
How to Overwrite Deleted Data with Cipher
Use the following command format to overwrite deleted data on a specific drive in Windows: Cipher.exe /w:drive letter. This command runs in Windows Terminal, ensuring old files are permanently gone. This process prevents your deleted information from being recovered. To get started, open the Windows Terminal app with administrator rights, then choose either Windows PowerShell or Command Prompt.
- Open the Windows Terminal app as administrator and select Windows PowerShell or Command Prompt. ⚠️ Requires admin privileges
- Use the command format below to overwrite deleted data on the specified drive on your Windows machine:
cipher /w:<drive letter>Replace
<drive letter>with the drive on your computer. - For example, run the command below to overwrite deleted data on the C drive:
cipher /w:C - Wait for the process to complete. It will overwrite all deleted data on the drive.
That should do it!
