Digital Forensics: Analyzing File Systems for Evidence

Every digital action leaves a footprint, but finding the truth requires knowing exactly where and how operating systems store data. Understanding the structure of file systems is the cornerstone of any successful digital forensics investigation. This text-based course guides you through the foundational concepts of file system forensics. You will learn how to look beyond the user interface to examine raw storage structures, trace file activity, and recover crucial evidence from deleted or hidden areas. What you'll learn: - Understand core file system concepts, storage structures, and sector-level layouts - Analyze metadata, timestamps, and file system journals to reconstruct user activity - Locate and extract hidden files, deleted data, and slack space remnants - Compare structures of major modern file systems including NTFS, ext4, and APFS - Apply forensic integrity methods using cryptographic hashing to preserve evidence - Interpret directory entries and partition tables to map out storage devices We begin with essential terminology and the physical-to-logical mapping of storage media. From there, you will progress to reading detailed file system structures, analyzing metadata, and identifying artifacts left behind by system and user actions. This course is designed for absolute beginners to digital forensics, cybersecurity enthusiasts, and IT professionals looking to build a strong foundation in storage analysis. No prior forensic experience is required. Start reading today to build your core skills in digital investigation and file system analysis.
