The Challenge of Making Deleted Files Unrecoverable
When you delete a file on Windows 10, the operating system marks the disk space occupied by the file as available for reuse. However, until new data is written to that space, the contents of the deleted file can still be accessed using specialized software designed for data recovery. This means that even if you delete a file and empty your recycle bin, someone with the right knowledge and tools could potentially recover those files.
The challenge lies in ensuring that the deleted files are overwritten with new data, making them irrecoverable. The methods we will discuss in this blog post will help you accomplish this goal by securely erasing the content of the deleted files, making them virtually impossible to recover.
Things You Should Prepare for
Before we dive into the methods, there are a few things you should prepare for to ensure a smooth process:
1. Backup: Before attempting to permanently delete your files, it is essential to create a backup of any important data. Mistakes can happen, and having a backup ensures that you don’t lose any crucial files in the process.
2. Storage Space: When you delete files, you need to have enough free storage space available to overwrite the deleted files. Make sure you have sufficient space on your storage drive to perform the methods discussed later in this blog post.
Method 1: Using File Shredder Software
Using specialized file shredder software is one of the most effective and convenient ways to make deleted files unrecoverable on Windows 10.
