Cairo Secure Eraser review
A free offline Windows shredder with multi-pass deletion for selected files and folders.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Cairo Secure Eraser is a free Windows desktop utility for permanently deleting selected files and folders through multi-pass overwriting. It is aimed at individuals and organizations removing sensitive data before disposal, resale, transfer, or routine deletion. Windows 7 through Windows 11 are supported, and the software operates locally and offline. File and folder permission handling is included, helping the utility work with selected items that may require permission-related handling.
The main strength is control over erasure depth. Cairo Secure Eraser offers four levels: 1-pass Quick, 3-pass Standard, 7-pass DoD 5220.22-M, and 35-pass Gutmann. Users can select individual files and folders or process multiple items in batches. Progress and completion reporting provide visibility during deletion, while detailed logs document the operation. The free plan includes securely deleting files and folders and four overwrite levels, with no paid tier described.
Its scope is deliberately narrow. Cairo Secure Eraser focuses on selected file and folder shredding rather than free-space or drive shredding, and its platform coverage is limited to Windows. That makes it a practical fit for Windows users who want configurable, offline multi-pass deletion without a subscription or paid upgrade. Organizations or individuals needing macOS or Linux support, scheduled jobs, or broader storage-erasure coverage should choose a tool built around those requirements instead.
