Data Shredder - Shred free space

Manage these settings at: Menu ▸ Settings (gear icon) ▸ Tools ▸ Data Shredder ▸ Customize ▸ Shred free space

Data Shredder provides a secure way to fully erase sensitive information so that data cannot be restored.

Shred Free Space

This operation makes the data from previously deleted files unrecoverable. You can select the method:

• Random overwrite - This is the simplest and quickest method. You can specify more passes for more security.
• DOD (Department of Defense) - This is a more secure but slower method. The file is overwritten with several types of data.
• Gutmann method - This is the slowest, but the most secure method. It is not possible to recover the original data by any known means.

Options

In Options you can choose which areas of file information to shred:

• Clean free disk space - Wipe free disk space of file contents which were previously deleted.
• Clean cluster tips - This refers to "gaps" in space which has been overwritten but can still contain data.
• Clean MFT (on NTFS) - Clean reference information from the data structure for NTFS disks.
• Clean FAT directory entries - Clean reference information from the data structure for FAT disks.
