Unused or free space is the storage drive space that doesn’t have accessible data. When you delete your unimportant files or folders from your storage drive, the unused or free space increases while the used space decreases accordingly.

Why is it essential to erase deleted data from unused or free space?
To safeguard your privacy, you must erase the deleted files from the unused or free space present on your computer’s storage drive as the data remains available on the drive’s free or unused space in an inaccessible state even after it is deleted. And, any data recovery software can scan and recover that deleted data. The data might contain your personal and financial information such as credit card details, social security numbers, personal photographs, etc. This information is sensitive and must be protected from unauthorized use.
So, you need to erase your deleted data to sanitize the unused or free space. The erased deleted data is removed permanently from the storage drive and cannot be recovered using any data recovery tool.
