refers to any type of data attached to a file, but not in the file on an NTFS system?

• A. NTFS
• B. RAM
• C. Alternate Data Stream (ADS)
• D. MBR

Answer: (C)

NTFS can attach additional data to a file via Alternate Data Streams. The main data stream holds the visible file content, while one or more extra streams can store any type of data without changing how the file appears when opened normally. These streams aren’t shown by standard file viewers, and you access or reveal them using special tools or commands that enumerate NTFS streams (for example, using a filename with a stream name like filename:streamname). This capability directly answers “data attached to a file, but not in the file” on an NTFS system. The other options describe the filesystem itself, memory, or disk structure, not per-file data streams.
