Eraser overwrites data instead of merely deleting it: right-click any file or folder and choose Erase, and its contents are written over using a selectable method, from a single pseudorandom pass to the US DoD 5220.22-M patterns or the 35-pass Gutmann method. Erasures can be run immediately, at restart or on a recurring schedule, the Recycle Bin can be wiped automatically, and a free-space wipe overwrites the unused parts of a drive so files deleted the ordinary way in the past can no longer be recovered with undelete tools. Version 6.2.0.2996 is GPLv3 open source and completely free. ## Deleting removes the index; Eraser removes the data Ordinary deletion only removes a file's **index entry**; the data itself sits on the disk until something else overwrites it, which is why recovery tools work. Eraser, from **Heidi Computers Ltd**, closes that gap properly: right-click any file or folder, choose **Erase**, and its contents are written over using a method you select — from a **single pseudorandom pass** to the **US DoD 5220.22-M three- and seven-pass patterns**, the 35-pass Gutmann method, or Schneier's method. The **task log shows exactly what was overwritten and whether any files were skipped because they were locked**, which is what makes the result auditable rather than assumed. Note the identity, because the name is crowded: this is the long-running GPLv3 open-source program, **not east-tec Eraser**, which is a separate commercial product, and nothing to do with the magic-eraser photo features in phone apps. Version 6.2.0.2996 is completely free. ## Targets and timing: files, the Recycle Bin, free space You choose the target, the overwrite standard, and the timing. Targets include a **file or folder**, the **Recycle Bin** — which can be wiped automatically — and **all the free space on a drive**: the free-space wipe overwrites only the unused parts, destroying remnants of files deleted the ordinary way in the past while leaving every current file untouched. Erasures can run **immediately, at the next restart, or on a recurring schedule** you set once and forget, and the right-click menu integration makes secure deletion a **two-click habit rather than a special procedure**. Scheduling at restart matters in practice, because locked or in-use files are otherwise skipped — one practical route when a Recycle Bin or folder erase keeps reporting locked files. ## Honest limits: SSDs and pass-count theatre Two honest limits matter more than any feature. First, overwrite methods were designed for magnetic hard drives: **on an SSD, wear-levelling and TRIM mean the drive may not write where Eraser asks**, so overwriting cannot be guaranteed — full-disk encryption or the drive maker's secure-erase tool is the right answer there. Second, the famous **35-pass Gutmann method is mostly theatre on modern drives and extremely slow**; a one-to-three-pass method is the sensible default, so reserve the heavy patterns for compliance checklists rather than real-world need. Version 6.2.0.2996 looks dated, but it is free, open source, and still the reference tool for this one job. Requirements are light — Windows 8.1, 10 or 11 with .NET Framework 4.8, 512 MB of RAM and 100 MB of space — and the caution with Eraser is about what it does, not what it is: it is designed to make data permanently unrecoverable, so choose targets carefully. ## Installation 1. **Download the official installer** — Download Eraser 6.2.0.2996 from the official Heidi Computers project on SourceForge using the button above and save the EXE to your Downloads folder. 2. **Run the installer** — Double-click the downloaded EXE and follow the setup wizard; Eraser adds its Erase entries to the Windows right-click menu and installs the scheduler service it needs for timed tasks. 3. **Erase your first file or schedule a wipe** — Right-click a file or folder in Explorer and choose Erase to overwrite it immediately, or open Eraser's schedule view to set up a recurring Recycle Bin or free-space wipe with your chosen overwrite method. ## Editorial verdict Deleting a file in Windows only removes its index entry; the data sits on the disk until something else overwrites it, which is why recovery tools work. Eraser by Heidi Computers closes that gap properly, and its strength is control: you choose the target — a file, a folder, the Recycle Bin, or all the free space on a drive — the overwrite standard, and whether the job runs now, at the next restart, or on a schedule you set once and forget. The right-click menu integration makes secure deletion a two-click habit rather than a special procedure, and the task log shows exactly what was overwritten and whether any files were skipped because they were locked. Two honest limits matter. First, overwrite methods were designed for magnetic hard drives: on an SSD, wear-levelling and TRIM mean the drive may not write where Eraser asks, so overwriting cannot be guaranteed — full-disk encryption or the drive maker's secure-erase tool is the right answer there. Second, the famous 35-pass Gutmann method is mostly theatre on modern drives and extremely slow; a one-to-three-pass method is the sensible default. Version 6.2.0.2996 looks dated, but it is free, open source, and still the reference tool for this one job. ### Strengths - Right-click Erase entries in Windows Explorer let you overwrite a file or folder securely in two clicks, instead of sending it to the Recycle Bin where its data remains recoverable. - A real scheduler runs erasures immediately, at restart or on recurring daily or weekly schedules, so the Recycle Bin and temporary folders can be wiped automatically without reminders. - Multiple overwrite standards are built in, including the US DoD 5220.22-M three- and seven-pass patterns, the 35-pass Gutmann method, Schneier's method and single-pass pseudorandom data. - The free-space wipe overwrites only the unused parts of a drive, destroying remnants of files deleted normally in the past while leaving every current file untouched. - It is GPLv3 open source and completely free with no paid edition, and each task ends with a log entry reporting what was erased and anything that could not be completed. ### Trade-offs - Overwriting cannot be guaranteed on SSDs, because wear-levelling and TRIM may redirect writes, so SSD sanitisation is better done with encryption or the manufacturer's secure-erase utility. - High-pass methods such as the 35-pass Gutmann pattern are extremely slow on large drives and offer no practical benefit on modern magnetic disks over one to three passes. - The interface and task dialogs are functional but dated, and locked or in-use files are skipped unless the erasure is scheduled to run at the next restart. ## FAQ **Is eraser for Windows safe?** Eraser by Heidi Computers is GPLv3 open-source software, so its code is public and it is completely free with no paid edition — the build here is version 6.2.0.2996. The caution is about what it does rather than what it is: it is designed to permanently overwrite files, so check the target and overwrite method before you run a task. **How can I securely delete files in Windows 11?** With Eraser, right-click the file or folder and choose Erase instead of Delete, and Eraser overwrites the data using a method you select — from a single pseudorandom pass to the US DoD 5220.22-M patterns. Jobs can run immediately, at restart or on a schedule, and a free-space wipe overwrites the unused parts of a drive so files deleted normally in the past cannot be recovered either. **Is there any free software for secure erase?** Yes — Eraser itself. It is free, open-source (GPLv3) software from Heidi Computers with no trial, paid edition or feature unlock, and it includes right-click erasing, the Recycle Bin wipe, scheduled tasks and multiple overwrite standards. **What is the best software to permanently delete files?** Eraser is the long-running reference tool for this job on Windows: you choose the target — a file, a folder, the Recycle Bin or all the free space on a drive — the overwrite standard, and whether the job runs now, at restart or on a schedule. One honest limit: overwriting cannot be guaranteed on SSDs because of wear-levelling and TRIM, where encryption or the drive maker's secure-erase command is the better answer. **What is a secure eraser?** A secure eraser overwrites a file's data instead of merely deleting it. Ordinary deletion only removes the file's index entry, leaving the contents recoverable until something else uses the space; a tool like Eraser writes over the data itself — once, or with multi-pass standards such as DoD 5220.22-M or the 35-pass Gutmann method — so recovery tools find scrambled data instead of your file. --- Source: https://filecobra.com/app/eraser-heidi-pc/ · Mirrored from the publisher's own release channel by FileCobra.
