In this post, I’ll show you how to shred free space to clean-wipe already delete files.
Why you need to shred free space
Clean-wiping your hard drive can be useful in many situations, especially when you are preparing your computer for sale. As you may already know, your deleted files that contained confidential information are not necessarily all gone. Some of them may have been overwritten with other files, but some of them are still there. You wouldn’t want your files to be recovered by someone, would you?
The best way to wipe everything from your hard drive is to format it. However, not all types of disk formatting delete all data from the disk. If you select a quick format method, your old data can still be recovered with the help of some file recovery software. Besides, you may not want to delete all files and programs including the operating system from your PC. If that’s the case, you should consider shredding free space with Easy File Shredder. Shredding free space will make traces of your deleted files unrecoverable without affecting any of your existing files or programs.
