SummaryThe classification of file fragments of various file formats is an essential task in various applications such as firewalls, intrusion detection systems, antiviruses, web content filtering, and digital forensics. However, the community lacks a suitable software tool that can integrate major methods for feature extraction from file fragments and classification among various file formats. In this article, we present Fragments‐Expert that is a graphical user interface MATLAB toolbox for the classification of file fragments. It provides users with 23 categories of features extracted from file fragments. These features can be employed by seven categories of machine learning algorithms for the task of classification among various file formats.
