How to erase files permanently from Windows computer?

Using a disk erasing tool. For complete data destruction, you can wipe the entire hard drive. This is useful if you are selling or donating your PC.

DBAN is a free, open-source software used to permanently erase data from hard drives. It is particularly useful when you want to securely wipe a hard drive before selling, donating, or recycling a computer. Unlike regular file deletion methods, DBAN ensures that the data cannot be recovered by overwriting it multiple times with random data.

Steps to Use DBAN for erasing files permanently on Windows:

1. Download DBAN: Download DBAN and create a bootable USB or CD.

2. Boot from DBAN: Restart your computer and boot from the DBAN USB/CD.

3. Select Wiping Method: Choose the number of passes for data wiping (the more passes, the more secure the erasure).

4. Start Wiping: DBAN will begin wiping the hard drive. It will take some time, depending on the size of the drive and the wiping method.

Limitations:

SSD Compatibility: While DBAN can wipe some SSDs, it is not as effective on them due to the way data is stored on SSDs (TRIM). SSDs require different tools or methods for secure erasure, such as using the manufacturer’s software or the built-in secure erase function in the drive’s firmware.

No GUI: DBAN operates through a command-line interface, so it may be intimidating for those unfamiliar with text-based interfaces.
