Eraser vs ZERDAVA File Shredder

Eraser is a free Windows security tool for overwriting sensitive data on drives. It can erase files and folders, previously deleted data, unused disk space and the current user’s Recycle Bin. Its methods include pseudorandom data and named overwrite schemes such as HMG IS5 and DoD 5220.22-M. Users can also define custom methods by choosing a number of passes and specifying text, hexadecimal or random data for those passes. A customizable scheduler handles recurring tasks and missed schedules. Optional Windows Explorer integration adds a context menu for supported items, and the help documentation lists a command line interface. The site lists support from Windows XP SP3 through Windows 11 and Server 2012–2025, and says Eraser works with drives supported by Windows. The download page cautions that erasure security has not been verified internally or externally and that the code may not remove all traces of files. Unused-space erasure on network drives may also require NAS knowledge and may not handle enforced quotas as expected, even when a task reports success. Eraser costs nothing.

ZERDAVA File Shredder securely erases files, folders, disks and removable media on Windows and Android. Its free-space wipe targets unused disk space, and it can erase USB sticks and SD cards. Before deletion, the product checks a password; afterward, it can generate a report. ZERDAVA says its software supports more than 20 international erasure standards, though available methods vary by version; Gutmann is the listed standard. The Windows Shredder plan costs $26 a year and includes a 7-day free trial. The Android Mobile Shredder plan also has a 7-day trial, but no price is listed. Supported systems listed in the FAQ are Windows 7, 8, 8.1 and 10, and Android 4.1 or higher. Windows downloads include online and offline installers in 32-bit and 64-bit versions, with English and Turkish options. Automatic updates are provided during the license period. For organizations, ZERDAVA describes solutions for servers and workstations, with a web-based management console in its enterprise solution. Its privacy policy says offline-scanned personal data stay on the device, while files with suspicious clues may be sent to its cloud service for examination.
