Can I use the shredder to overwrite the free space from deleted files without deleting other files
Hello again.
The process you are referring to is called "wiping free space".
When you delete or empty a file, Windows removes the reference to that file but doesn’t remove the actual data that made up the file from your hard disk. Over time, this data will be overwritten as Windows writes new files to that disk area. However, the files can be easily recovered by data recovery software. Given the right recovery program, someone could reconstruct all or parts of the files that you’ve deleted. For privacy and security reasons, you can set it to wipe the free areas of your hard drive so that deleted files can never be recovered.
But, Bitdefender doesn't have an option to wipe free space.
For that purpose, you need apps like Glary Utilities, BleachBit, etc.
Regards.
Thank you kindly for your input. I will check out the apps you mentioned.
