Summary: In this blog, we will discuss the best five tools that will help you permanently erase files and prevent data recovery from your Windows PC. You can review these tools based upon their features, ease-of-accessibility, data erasure results, etc., and choose the best one as per your needs.
In today’s digitally empowered world, safeguarding one’s privacy and confidential data is of utmost importance, especially when the data protection laws are not stringent and filled with loopholes in most nations.
Therefore, it is important to encrypt your data or use password protection to avoid any type of data theft or misuse.
The use of antivirus & anti-malware tools is another way of ensuring data privacy. However, it is of important that you use a data erasure software to permanently erase sensitive files on your PC.
But, almost all of these devices (hard drives, SD cards, smartphones, laptops, etc.) are discarded, sold, or donated at the end of their life cycle without proper data sanitization.
Furthermore, deleted data can be easily recovered from any storage media, whether a USB thumb drive, HDD, SSD, SD card, etc., using data recovery software and services.
Therefore, you must permanently erase the files/folders to protect and safeguard your data against unwarranted data misuse.
Best tools for permanent data erasure beyond the scope of recovery
Data erasure software uses different standards for data erasure hosting various algorithms. These algorithms decide the effectiveness of the software.
Some of the popular algorithms used by the best data erasure software are the U.S. Department of Defense (DoD 5220-2 M), Gutmann, etc.
Although there are several tools available to choose from, most of them aren’t capable of complete data sanitization.
Therefore, to save you unnecessary efforts, we shortlisted the five best tools available to erase files and folders from your Windows PC beyond the scope of recovery.

Moreover, the Stellar File Eraser uses three international data erasure algorithms, including Zeroes (Single Pass), Pseudo Random (Single Pass), and U.S. Department of Defense DoD 5220-2 M (3 Passes), which ensures that the data is completely erased from the device.
This powerful data erasure tool is capable of the following.
- Erasure of system activity traces and installed application traces
- Complete erasure of internet activities and cookies ensuring 100% privacy against online threats
- Supports erasure of deleted data to secure the system and optimize storage space
- Option to create an erasure list facilitating multiple file erasure in a single step.
- Search files with file name or extension.
- Schedule automatic erasing of files at specified intervals.
- Option to add important files to Ignore list, thus safeguarding them against erasure process.
Drawbacks
- Free version is not available
- Requires more time for recovery with a high-standard algorithm.
2. Hard Disk Scrubber
This is a free disk and file scrubbing tool from Summit Computer Networks Inc. designed to destroy sensitive data from a Windows PC.
The tool overwrites free space on Windows drives and deletes the file permanently beyond recovery.

There are two major functionalities in Hard Disk Scrubber viz. Hard Disk Free Space Scrubbing option, and the File Scrubbing option.
The tool offers five scrub types that are a combination of six scrub patterns arranged into passes:
- Normal: Uses a Random pattern with a single pass
- Heavy: Uses Zeroes, Ones, and Random patterns with three passes
- Super: Uses 5 patterns with 5 passes
- Ultra: Uses DoD prescribed overwriting with verification
- Custom: User can define their own pattern with as many passes as required
Drawbacks:
- Does not wipe/erase folders and sub-directories
- Not safe as it can also wipe Windows system and program files
3. Eraser
Eraser is a security tool for Windows that erases data from storage drives by shredding and overwriting it several times with selected patterns.
The tool helps maintain privacy and allows users to remove selected files instead of wiping the whole drive.

The tool also provides an option to schedule erasers of specific files on the system based on date and time.
The software uses the following algorithms to erase data from storage media:
- Write Zero
- Gutmann
- Random Data
- DoD 5220.22-M
- HMG IS5
- GOST R 50739-95
Drawbacks:
- Doesn’t have a user-friendly interface
- Doesn’t verify destroyed data
4. Hard Wipe
Hard Wipe erases the entire hard drive or portable storage media and ensures that no one can recover sensitive information.
This tool also comes in a portable edition that runs from a USB drive and lets you wipe the entire disk without installation.
However, the portable version offers more functionality; thus, it requires a professional upgrade.
