To clean unused disk space using File Shredder (often referred to as FS File Shredder), you need to use its built-in “Shred Free Disk Space” feature. This process safely overwrites unallocated sectors of your hard drive so that previously deleted files cannot be recovered using forensic software.
Here is the step-by-step guide to doing it safely and effectively. How to Shred Free Disk Space Open the Application: Launch File Shredder on your desktop.
Access the Tool: Click on Shred Free Disk Space located in the left-hand menu panel (just above the Settings link).
Select Your Drive: Check the box next to the hard drive volume(s) (e.g., C:, D:) that you want to wipe.
Choose a Shredding Algorithm: Select your preferred data-wiping method from the drop-down menu.
Confirm and Run: Click Next, review your summary, and click Start to begin the process. A progress bar and elapsed time counter will show you the status. Selecting the Right Algorithm
File Shredder offers five distinct erasure algorithms. The more “passes” an option has, the more times random data or zeros are written over the empty space.
Simple One Pass / Two Pass: Fastest options. Writing a single pass is generally considered secure enough for modern hard drives.
DoD 5220.22-M: A 3-pass military-grade standard. This is the ideal balance of high security and reasonable processing time for most users.
Secure Algorithm (7 passes): Highly secure but takes longer.
Gutmann Algorithm (35 passes): The most extreme security method available. It is generally unnecessary for modern drives and will take an exceptionally long time to complete. Important Things to Keep in Mind
