A file shredder and file eraser app is a software tool designed to securely delete files from a storage device. When files are deleted using the regular delete function, they are often still recoverable with specialized software. A file shredder or file eraser app uses advanced techniques to overwrite the data of the file multiple times, making it virtually impossible to recover.
Benefits of using a file shredder or file eraser app include:
- Security: By securely deleting files, you ensure that sensitive information cannot be accessed by unauthorized individuals, protecting your privacy and preventing potential data breaches.
- Compliance: In certain industries or jurisdictions, there may be legal requirements to securely erase sensitive data. Using a file shredder or file eraser app helps ensure compliance with these regulations.
- Protection from identity theft: When you dispose of a device or sell it, it's important to securely erase all personal and sensitive data to prevent identity theft. A file shredder or file eraser app helps you completely remove your data from the device.
- Peace of mind: By using a file shredder or file eraser app, you can have peace of mind knowing that your deleted files are irrecoverable, reducing the risk of data leaks or unauthorized access.
It's important to note that using a file shredder or file eraser app should be done with caution, as once the files are securely deleted, they cannot be recovered. It is advisable to double-check and ensure that you are deleting the intended files before using such applications.

What is the Gutmann method?
The Gutmann method is a data wiping method that was developed by Peter Gutmann, a computer scientist. It is known for its thoroughness and involves overwriting data with a series of carefully selected patterns, totaling 35 passes.
The Gutmann method was initially designed to securely erase data from older magnetic storage media, but it is considered unnecessary for modern storage technologies.
Modern storage devices, such as solid-state drives (SSDs), employ their own secure erase mechanisms that render the Gutmann method obsolete.
