File Shredder: Safeguard Your Data with Secure Deletion on Linux
When you delete any file from any operating system (Linux, Windows, etc.), the story isn't as simple as it seems. The operating system doesn't immediately delete the data; instead, it marks the space on your hard drive as available and removes the file from the directory structure.
This means that, until overwritten, the actual data remains on your disk. This leaves room for potential security breaches, as determined actors could recover seemingly deleted files and gain access to sensitive information.
Well, you need to take advantage of software such as "File Shredder", which manually replaces the 1s and 0s on your disk to completely remove the data forever.
