We always worried about compromising our personal data online, so we do all the necessary steps to protect our online accounts. But we forget to safeguard our system offline. In this article, we are going to share some best tools that will help you to permanently delete files securely from your computer and make them impossible to recover by anyone.
Yes, sometimes without even hacking our online accounts, others can access our personal files. Did you know even if we delete files or format drives (no matter how many times) from our system, some powerful tools out there can recover most of our files?
Just imagine you sold your old laptop/PC and you make sure to delete your personal files and format drives multiple times believing that your system was cleaned before selling. Are you 100% sure still no one can recover your deleted files with any file recovery software?
Then you are wrong — about 50% of your files still recoverable. You didn’t know which files will come under that 50% — it may be your private photos or some important office documents or anything. So it doesn’t hurt to delete your files securely from your system. But how do delete them permanently?
In this article, we are going to introduce some tools to help you with this process. These tools will permanently delete files from your PC and also make them impossible to recover with hard drive recovery tools.
You shouldn’t use these tools if your data is saved on a SSD. Writing cycles on SSDs are limited, so the controller tries to utilize the memory evenly. It’s impossible for software to control where the data is physically located on a SSD drive.
