What is Permanent Data Eraser for Windows?
Permanent Data Eraser for Windows permanently removes files by overwriting their contents before deletion. It can shred selected files and folders, wipe unused drive space without touching existing files, or erase an entire non-system drive. The program includes several overwrite methods, checks the drive type before erasing, and can verify written data after a shred job. It can also save a PDF certificate showing the details of a completed erasure.

Key Features
- Erase files, folders, the free space of a drive, or a whole non-system drive.
- Overwrite methods from one pass to Gutmann (DoD, VSITR, HMG IS5, Schneier, NIST 800-88 or a custom pattern).
- Verify option reads every byte back afterwards to confirm the new pattern is really there.
- Save a PDF Certificate of Data Erasure for an audit, a client or the next owner of the hardware.
- Detects SSDs and flash drives and tells you plainly where overwriting is not reliable, pointing you to the drive’s own Secure Erase or NVMe Sanitize.
- One-click cleanup of Windows temp folders, the Recycle Bin, recent documents, jump lists and browser history (Chrome, Edge, Firefox, Brave, Opera, Vivaldi).
- Remote wipe from your own Telegram bot: send /wipe if a laptop is lost or stolen and the folders you marked are erased.
- The system drive is shown but cannot be selected, so a stray click will not wipe the running Windows.
