Windows App

Secure File Shredder

Permanently delete files beyond any recovery — on both SSDs and HDDs. Auto-detects your drive type and applies the method that actually works.

Features

Hybrid SSD & HDD Detection

Automatically detects whether each file is on an SSD or HDD and applies the correct deletion method per file — no configuration needed.

AES-256 for SSDs

Encrypts the file with a random AES-256 key, then destroys the key. Even if data is recovered from SSD spare areas, it is mathematically unreadable.

DoD 7-Pass for HDDs

Traditional DoD 5220.22-M certified 7-pass overwriting for mechanical drives. Physically rewrites sectors so original data cannot be recovered.

Drag & Drop

Drag files or folders directly onto the app window to add them to the shred queue. Works alongside the standard file browser.

Recycle Bin Shredder

A dedicated tab for securely emptying the Recycle Bin. Applies the same hybrid SSD/HDD method to everything waiting for deletion.

10–50× Faster on SSDs

The encryption method is far faster than traditional overwriting on SSDs. A 100 MB file takes 2–10 seconds versus 1–2 minutes with overwriting.

Manual

Installation

Requires Windows 10 or later.

Install from Microsoft Store.

Why Standard Deletion Is Not Enough

When you delete a file normally, Windows only removes the pointer to the data. The actual bytes remain on disk until overwritten by something else — and can be recovered with widely available tools.

Traditional overwriting (writing zeros or random data over the file) works well on HDDs but does not reliably work on SSDs. SSDs use wear levelling and spare areas that redirect writes, so overwritten data may still exist in another block.

Secure File Shredder solves this by using encryption on SSDs: even if the original data is physically present somewhere on the SSD, it is encrypted with a destroyed key and mathematically unreadable.

Shredding Files
  1. Launch Secure File Shredder.
  2. Go to the File Shredder tab.
  3. Add files by clicking Add Files or dragging them onto the window.
  4. Click Shred.
  5. Confirm the deletion prompt — this action cannot be undone.

The app detects each file’s drive type and applies AES-256 (SSD) or DoD 7-pass (HDD) automatically. Progress is shown in real time.

Shredding the Recycle Bin
  1. Go to the Recycle Bin tab.
  2. The app lists what is currently in the Recycle Bin.
  3. Click Shred Recycle Bin.
  4. Confirm the prompt.

For full access to the Recycle Bin, run the app as Administrator (right-click the icon and choose Run as administrator).

System Protection

The app blocks deletion of files inside protected system folders including Windows, Program Files, and ProgramData. This prevents accidental damage to your operating system.

If you need to shred files in other sensitive locations, ensure you have the appropriate permissions and run the app as Administrator.
