It is not ideal to rely on a simple DOS copy for copying files because:

• A. A simple DOS copy will not include deleted files, file slack, and other information.
• B. It is slower than imaging.
• C. It creates encrypted copies.
• D. It changes file timestamps.

Answer: (A)

In digital forensics, preserving all data on the media is essential. A simple DOS copy copies only the visible file data, not the surrounding evidence that can live outside active files. Deleted files sit in unallocated space and can sometimes be recovered if the capture preserves that space. File slack—leftover bytes in the blocks a file occupies—can contain remnants of previous data, and other hidden artifacts (such as certain metadata or alternate data streams) may not be carried by a basic copy. Because of this, a simple copy can miss meaningful evidence and hinder a thorough analysis. Imaging, by contrast, creates a sector-by-sector copy of the entire drive, including unallocated space, slack space, and filesystem metadata. This preserves the full structure and potential artifacts needed for forensic examination, such as recovering deleted data, performing data carving, and accurately reconstructing timelines. The other options aren’t the primary issue here: encryption isn’t automatically applied by a basic copy, and while timestamps can be touched during copying, the real limitation is the incomplete capture of the evidence space.
