Permanently deleting files from your Windows computer is essential for maintaining data security and ensuring that sensitive information cannot be recovered. In this guide, we will explore the various methods to achieve file deletion beyond recovery, including the use of software tools designed for this purpose.

Problem: Insecure File Deletion

When you delete a file from your computer, it is not actually removed from the storage medium. Instead, the file system marks the space occupied by the file as available for reuse. Until that space is overwritten with new data, the deleted file can potentially be recovered using specialized software.


  1. Unintentional deletion
  2. Outdated file deletion methods
  3. Lack of awareness about secure deletion


Solution 1: Secure File Deletion using Windows Command Prompt

The Windows Command Prompt provides a powerful method for permanently deleting files. Follow these steps:

  1. Open the Command Prompt by searching for 'cmd' in the Windows Start Menu.
  2. Navigate to the directory where the file is located using the 'cd' command.
  3. Once in the correct directory, type 'del /F filename.extension' to delete the file permanently.
  4. Press Enter to execute the command.
  5. Repeat the process for each file you want to delete permanently.

Solution 2: Secure File Deletion using Third-Party Software

Several software tools exist that specialize in secure file deletion. One recommended tool is CCleaner. Here is how you can use it:

  1. Download and install CCleaner from the official website.
  2. Launch CCleaner and navigate to the 'Tools' section.
  3. Click on 'Drive Wiper' to access the secure file deletion feature.
  4. Select the drive where the files are located and choose the appropriate deletion method.
  5. Click 'Wipe' to begin the secure file deletion process.

Solution 3: Secure File Deletion using Encryption Tools

Encrypting files before deletion adds an extra layer of security, making it virtually impossible to recover the original data. One popular encryption tool is VeraCrypt:

  1. Download and install VeraCrypt from the official website.
  2. Create a VeraCrypt volume and mount it on your computer.
  3. Copy the files you want to delete to the mounted volume.
  4. Unmount the VeraCrypt volume and securely delete it by following the steps mentioned in the previous solutions.

Software Recommendation:

In addition to CCleaner and VeraCrypt, another highly recommended software tool is Eraser. Eraser provides advanced file deletion options, including secure file erasure and file shredding. It is widely recognized for its reliability and user-friendly interface.
