Stage 2: Permanently Erase Files, Folders, Traces
The File Eraser software offers the following erasure options that are explained in detail below:
- Erase Free Space: This option enables you to securely wipe the ‘Free Space’ on selected volumes, including local drives (C, D) and network drives.
Note: Free space on a drive may contain traces of deleted files that remain recoverable until overwritten. While it appears as available storage, the operating system only removes file references, leaving the actual data intact. Securely erasing free space prevents recovery, ensuring privacy, compliance, and safe device reuse.
Choose the volume where you want to erase free space and click ‘Erase Now.’ (Refer to Image 7)
Click on ‘Proceed’ on the Confirm Erasure screen; the software will erase the free space, ensuring that previously deleted data is no longer recoverable.

- Erase Volume: You can erase an entire volume using the option; however, the software does not harm the Operating System, so even if you select the C drive, the OS files remain intact.
Select the ‘Volume,’ which you want to erase, and click ‘Erase Now.’ (Refer to Image 9)
Click ‘Proceed’ on the ‘Confirm Erasure’ screen.

You have successfully wiped files, folders, traces, and volumes from your system. This helps maintain device hygiene, permanently removes sensitive data, and reduces the risk of data leakage and breaches. This tool comes in handy to IT Admins during Data Minimization.
Regular data erasure is essential, especially when information has served its purpose to comply with data protection laws and standards like EU-GDPR, CPRA, HIPAA, and ISO 27701. Securely wiping data safeguards privacy, enhances security, and meets compliance requirements.
