Shreddr

A lightweight, portable drag-and-drop tool for securely shredding and deleting files. Shreddr overwrites file data with random bytes, renames the files to obscure metadata, and then permanently deletes them.

How It Works

1. File Overwriting:

   • Shreddr overwrites the file's contents multiple times with random bytes, making the original data difficult to recover.

2. File Renaming:

   • Between overwrite passes, Shreddr renames the file to a random UUID to obscure its metadata (e.g., file name, timestamps).

3. File Deletion:

   • After overwriting and renaming, the program permanently deletes the file.

4. Drag-and-Drop Interface:

   • The program provides a simple GUI where users can drag and drop one or multiple files to shred them.

5. Confirmation Prompt:

   • Before shredding, Shreddr displays a Yes/No confirmation prompt listing all the files to be shredded. This prevents accidental shredding and allows users to review the files.

6. Summary Prompt:

   • After shredding, Shreddr displays a summary of all successfully shredded files and any files that failed to shred.

Why Use Shreddr Instead of the Recycle Bin?

Aspect	Recycle Bin	Shreddr
File Deletion	Files are only moved to the recycle bin and can be easily restored.	Files are overwritten with random bytes, renamed, and permanently deleted.
Data Recovery	Files can be recovered using basic tools, even after emptying the recycle bin.	Overwriting and renaming make recovery much harder, especially after multiple passes.
Metadata Removal	Metadata (e.g., file name, timestamps) remains intact.	Metadata is obscured by renaming the file to a random UUID during the shredding process.
Security	Minimal security; files are still present on the disk.	Provides a secure method of deletion, especially for casual use cases.
Ease of Use	Simple drag-and-drop to the recycle bin.	Shreddr also provides a drag-and-drop interface for ease of use.

Disclaimer

Shreddr is designed for casual use and may not meet the requirements for advanced data recovery prevention. Use at your own risk, and ensure you have backups of important files before shredding them, as this process is irreversible.
