Hello,<br />
When it says extra data, it is referring to Alternate Data Streams, a feature built into NTFS. &nbsp;The thumbs.db file is basically a file that uses ADS that acts as a form of metadata (Data to describe other data) that lets you view thumbnails quicker in Windows XP. &nbsp;There is nothing to worry about.

Is &quot;THUMBS&quot; file a threat?

Security is the protection of information systems from theft or damage to the hardware, the software, and the information on them, as well as from disruption or misdirection of the services they provide. The main goal of security is protecting assets, and an asset is anything of value and worthy of protection.  Information Security is a discipline of protecting information assets from threats through safeguards to achieve the objectives of confidentiality, integrity, and availability or CIA for short. On the other hand, disclosure, alteration, and disruption (DAD) compromise the security objectives.
