Alternate File Shredder

Alternate File Shredder is a free, open-source Windows utility for deleting selected files and folders and overwriting drive free space. It is best suited to people who want those focused cleanup tasks without paying for a broader suite. It does not erase entire drives or schedule shredding.

Overview

The distinction between removing selected items, clearing traces of earlier deletions, and erasing a whole drive matters. Alternate File Shredder covers the first two: it permanently deletes files and folders, and can overwrite free space to prevent recovery of previously deleted data. That makes it useful for targeted cleanup, but not for preparing an entire drive for disposal or reuse.

The maker describes the program as freeware and open source. It also warns that users run it at their own risk and should consider carefully which files they select. That caution is appropriate for a utility whose purpose is irreversible deletion.

Key features

Deletion and free-space overwriting

File and folder deletion handles items you select directly; free-space wiping addresses data left behind after earlier deletions. The second function is a useful addition for users who have already removed files but want to reduce the chance of recovering them. Neither function amounts to whole-drive wiping, which this program does not support.

Overwrite templates

Users can choose a specific value, random values, or file content as the overwrite template. This gives some control over what is written during overwriting, though it does not change the program’s narrow focus or add scheduling.

Pricing

The Freeware plan costs nothing and includes file and folder deletion, free-space wiping, and advanced overwrite methods on Windows. There is no paid tier to weigh against it: the trade-off is scope, since drive wiping and scheduled shredding are absent.

The plan supports Windows Vista, 7, 8, 8.1, 10, 11, and Server, and requires .NET Framework 2.0. The maker says that framework has been included in Windows since Vista. The current listed version is 3.100, dated 13.02.2026.

Platforms

This is a Windows-only program, with support listed for Vista, 7, 8, 8.1, 10, 11, and Server. Its included languages span 20 options, including English, German, Spanish, French, Chinese, and Japanese. Users on Linux or macOS will need another tool.

Who it's for

Choose Alternate File Shredder if you use Windows and need free, focused deletion of selected files or folders, or want to overwrite free space after removing files. Look elsewhere if you need to erase a complete drive, automate shredding on a schedule, or use another operating system.

Pros and cons

• Pros: Free and open source, with both selected-item deletion and free-space wiping in one Windows utility.
• Pros: Three overwrite-template choices and support for 20 included languages make it more adaptable than a single-choice, single-language tool.
• Cons: No drive-wiping function, so it cannot handle whole-disk erasure.
• Cons: No scheduled shredding, making it a manual rather than automated cleanup option.
• Cons: The maker puts use at the user's own risk and urges care when selecting files, so mistaken choices carry particular weight.

Verdict

Alternate File Shredder is a sensible pick for Windows users who want a free, open-source way to delete selected files and folders and overwrite previously deleted data in free space. Its focused feature set is also its main limitation: choose another tool if you need whole-drive erasure, scheduled work, or support beyond Windows.
