Which of the following file types are commonly analyzed in digital forensics?

The chosen answer encompasses a broad range of file types that are frequently encountered and analyzed in digital forensics investigations. Digital forensics aims to uncover, preserve, and analyze data from various sources to investigate incidents ranging from cybercrimes to data breaches.

Analyzing documents, images, videos, and system files allows forensic experts to gather vital information related to user activities, system configurations, and potentially incriminating evidence. Documents can reveal communications, financial transactions, or sensitive information that is critical to a case. Images and videos can provide visual context that may help establish timelines or identify individuals or locations relevant to an investigation. System files are essential as they include logs and other data that can help reconstruct events or activities that took place on a device.

In contrast, other options presented have more limited scopes. Focusing solely on executable files, for instance, can exclude a wealth of crucial evidence contained in non-executable file types. Similarly, analyzing only audio files or a narrow set of data types would fail to provide the comprehensive insights typically required in digital investigations. Hence, option B, with its wide-ranging inclusion of various file types, is a natural fit for the digital forensics field.
