Maybe your Windows computer has a lot of important files, and you don't need them anymore. Besides, you want to trade in or donate this old computer. In this case, you'll need a file shredder for Windows to remove all your files permanently, especially sensitive data.
Luckily, now you can read this review and get 12 file shredders. Check their advantages and disadvantages to decide which one is the best for you.
Part 1: Why Do We Need a File Shredder?
When you delete a file on your computer and even empty the Recycle Bin, the data is not actually removed from your hard drive. Instead, the operating system simply removes the "pointer" or reference to the file in the file system table, marking the space the file occupied as "available" for new data. The original data remains on the disk until it is eventually overwritten by a new file.
This creates a significant security and privacy risk. Until that space is overwritten, anyone with basic data recovery or undelete software can easily retrieve your supposedly deleted files, including sensitive documents, financial records, confidential business information, or private photos.
Thus, File shredders are essential for:
- Ensuring personal and sensitive information cannot be recovered when you delete it.
- Erasing the remnants of already deleted files that still exist in the unallocated space on your drive.
- Securely cleaning a computer, hard drive, or external storage device before selling, donating, or recycling it.
Part 2: Best File Shredder for Windows 11/10 - 12 Options
The market offers numerous file shredding tools, each with its own features, strengths, and supported data erasure algorithms (like DoD 5220.22-M, Gutmann, etc.). Here is a breakdown of several top-rated options for Windows 11/10/8/7 users.
2.1 Windows Cipher Utility
The built-in Windows cipher command-line utility can be used to securely wipe the free space on an NTFS volume. While not a dedicated file-shredder for actively deleting files, it's a free, native file shredder to sanitize the remnants of previously deleted files.
Supported sanitisation:
> Pass 1: Overwrite with zeros;
> Pass 2: Overwrite with ones/maximum value (0xFF);
> Pass 3: Overwrite with random data.
| Advantage | Disadvantage |
|---|---|
| 1. Built-in to Windows: No need to download or install third-party software. | 1. Wipes Only Free Space: It does not directly shred active files; you must delete the files first. It then wipes the resulting free/unallocated space. |
| 2. Free and Reliable: A no-cost, Microsoft-supported tool that uses a robust three-pass sanitization method. | 2. Slow Process: Overwriting all unallocated space, especially on a large hard disk drive (HDD) with significant free space, can take many hours. |
3. Easy to Use (Command-wise): The command is simple (cipher /w:C:\Path\to\Directory) once the command prompt is open. |
3. Command-Line Interface (CLI): Requires using the Command Prompt or PowerShell, which is less user-friendly than a graphical user interface (GUI). |
| 4. Prevents Basic/Mid-level Recovery: The three-pass overwrite is highly effective against common data recovery software. | 4. May Not Wipe All Traces: It can fail to erase certain system artifacts, such as metadata within the Master File Table (MFT) or files stored in Volume Shadow Copies (Shadow Volumes). |
| 5. Works on NTFS Volumes: Designed to work directly with the NTFS file system used by most modern Windows versions. | 5. Inconsistent on SSDs: Due to wear-leveling and TRIM technology in Solid-State Drives (SSDs), software-based overwriting (like Cipher) is less reliable. |
2.2 iReaShare Data Wipe
iReaShare Data Wipe is a professional-grade erasure tool that securely deletes files, folders, and entire drives. It supports multiple wiping algorithms, including DoD 5220.22-M, and can also erase free disk space. Its clean interface and advanced features make it ideal for businesses and individuals who value simplicity and reliability.
Supported sanitisation: Single one erasure, overwrite twice with random data, and DoD 5220.22-M standard
| Advantages | Disadvantages |
|---|---|
| 1. Comprehensive Erasing Functions It offers three main wiping modes, exceeding the capability of Windows' built-in `cipher /w` which only clears unallocated space: - File Shredder: Permanently deletes selected active files and folders. - Drive Wiper: Wipes the entire hard drive, SSD, or external device. - Free Space Erase: Thoroughly cleans data traces left by previously deleted files. |
1. Reliance on Paid Software iReaShare Data Wipe is third-party commercial software, usually requiring a paid license for full functionality, unlike the free, built-in Windows Cipher utility. |
| 2. Supports Industry Standard Algorithms Its Deep Erase mode is capable of supporting well-known security standards, such as the: - U.S. Department of Defense DoD 5220.22-M standard, which ensures data cannot be recovered by software or even hardware-based forensic methods. |
2. SSD Erase Limitations Like all software-based wiping tools, its effectiveness on Solid State Drives (SSDs) can be limited by firmware technologies such as wear-leveling and over-provisioning. |
| 3. User-Friendly Interface It provides a Graphical User Interface (GUI), allowing users to easily select files, folders, or entire drives for wiping with simple clicks, which is more intuitive and convenient than the command-line `cipher` utility. |
3. Performance and Speed The Deep Erase (multi-pass overwrite) feature, while secure, can be very time-consuming when run on large-capacity modern hard drives. |
| 4. Flexible Erase Modes It offers both a Quick Erase and Deep Erase mode, allowing users to choose a balance between security needs and time constraints. Erase USB flash drives, SD cards, and more external storage devices. |
4. Lack of Independent Verification As commercial software, the thoroughness of its data destruction relies on the company's claims, potentially being less transparent than some widely certified, enterprise-grade data destruction tools. |

Supported sanitisation: DoD 5220.22-M, and custom overwrite passes
| Advantages | Disadvantages |
|---|---|
| 1. Free and Official Microsoft Tool It is a free tool officially provided and supported by Microsoft (as part of the Sysinternals suite). |
1. Command-Line Only Interface It is strictly a command-line utility, which requires users to be comfortable with the Command Prompt or PowerShell, making it less accessible for non-technical users. |
| 2. DoD Standard Implementation It implements the US Department of Defense (DoD 5220.22-M) clearing and sanitizing standard by default, giving users confidence in the deletion process. |
2. Outdated Wiping Standard The DoD 5220.22-M standard is considered outdated for modern compliance requirements (which favor NIST SP 800-88 Rev. 1) and may not be fully effective on SSDs. |
| 3. Portability and Small Footprint It is a tiny, portable executable that does not require installation (just extraction), making it easy to run from any location or removable drive. |
3. Does Not Shred File Names in Free Space When wiping free space, SDelete securely overwrites the file data, but it does not securely overwrite the file names located in the free space of the Master File Table (MFT). |
| 4. Target Specific Files or Free Space It offers distinct functions to securely shred existing files/folders and to cleanse the unallocated (free) space on a volume to remove traces of already deleted files. |
4. Susceptibility to Silent Failure In rare cases (e.g., if a drive disconnects or errors occur during a lengthy wipe), SDelete may report "cleaned" even if the process was not fully completed, potentially leaving data unwiped without notification. |
2.10 Freeraser
Freeraser provides a unique drag-and-drop experience - simply drag files to its on-screen trash bin icon to shred them. It offers three security levels and is easy to use, making it great for casual users who want quick, secure deletions.

2. Interface and Usability are Basic The user interface is minimalist and may feel outdated or less intuitive compared to modern Windows utilities, which could be a drawback for novice users. |
| 3. Effective Data Sanitization Utilizes a range of patterns (Zeroes, Ones, Random Data, etc.) across its different modes to ensure the original data is thoroughly obscured and cannot be recovered by forensic software. |
3. Potential for Long Processing Times Wiping the free space on a large hard drive, especially when using a multi-pass method like the "Super" or "Ultra" modes, can take a significant amount of time. |
| 4. Freeware and Portable It is completely free to use and often available as a portable application, meaning it can be run directly from a USB drive without installation. |
4. Overwrites SSDs with Multiple Passes Using high-pass modes on Solid State Drives (SSDs) is generally not recommended, as it causes unnecessary wear without increasing security due to the way SSDs manage data. |
Part 3: Q&A About File Shredder for Windows
Q1: How does shredding work on Windows?
In general:
- The tool selects the file(s) or drive/space to wipe.
- It overwrites the data area with random data (or specific patterns) one or more times.
- Then the file record is removed and the space marked available again.
- Some tools can also "wipe free space" so that previously-deleted files (which left residual data) are overwritten.
Q2: Does shredding work the same on SSDs (solid-state drives) as on HDDs?
No, there are special considerations. SSDs have wear-leveling, over-provisioning, and may not guarantee that overwriting a logical block actually overwrotes the physical cell. Some tools or methods may not fully guarantee unrecoverability on SSDs. Thus, if you are dealing with an SSD, checking whether the tool supports SSDs and using recommended methods is important.
Q3: What should I check in a good file shredder?
Some important criteria:
- Supports secure overwrite methods (e.g., random data, standards like DoD 5220.22-M).
- Ability to shred files/folders and optionally wipe free space.
- Compatibility with your storage type (HDD, SSD, USB).
- Ability to integrate with Windows (e.g., right-click context menu).
- Transparent documentation (how many passes, which algorithm).
- Trusted source (no malware).
Conclusion
Relying solely on the standard "Delete" button is a fundamental security oversight. A file shredder is a non-negotiable tool for maintaining digital privacy and security on any Windows 11 or Windows 10 computer. This review now provides 12 options above, and you can select one based on their pros and cons.
If you want a reliable, ad-free, and easy-to-use file shredder, iReaShare Data Wipe will be one of the most suitable choice, even though it is not a totally-free tool. However, you can easily erase specific files, folders, wipe hard drives, external storage devices, and wipe free storage only.
