![]() ![]() These risks apply to both live data and data at rest when devices are sold or disposed of. The importance of securely erasing files can be gauged by understanding the privacy and security risks associated with dark data, data at rest, ROT (Redundant Obsolete Trivial) data, or residual data on storage devices. However, files, folders, and applications are erased in the former, leaving the OS intact. The latter erases data on the entire drive leaving nothing behind, including the operating system (OS). File Erasure is confused at times with Drive Erasure. This method makes recovery of the erased data impossible, even in a laboratory setting. File erasure involves overwriting the data with binary 1’s & 0’s or a pseudorandom character. ![]() A file eraser software can also securely and irreversibly erase folders, partitions, applications, internet cache, and other data traces from a storage device. What Is File Erasure & Its Importance?įile erasure is the method of permanently erasing files. Therefore, it’s vital to understand the difference between deleting and securely erasing files. A freely available DIY data recovery software can recover the data from these devices, compromising business and stakeholder information confidentiality. Despite the sensitivity of the information held on personal and professional computers, most people are unaware that simply deleting files or formatting the device is not a secure method of wiping data from them. Knowing how to securely erase files from your device (PC, laptop, or Mac) is essential because if you don’t, sensitive information stored on your device can be retrieved, compromised, and misused. This blog provides an overview of file erasure, how to erase files, its importance, and methods of achieving secure file erasure. Therefore, secure erasure of files is necessary to ensure that the sensitive data does not fall into the wrong hands. However, deleting or formatting data from the device can be detrimental to data security and often leads to data leakage. Summary: Securing data while using the device, or when it changes hands, is resold, and is disposed of remains a priority for organizations and stakeholders alike. ![]()
