![]() The $MFT contains a significant part of the file system metadata, it also contains the content of very small files (those that fit within the MFT entry). ![]() The MFT entry can also be filled with 0-byte values, indicating it is empty (or unused), or have a special purpose signature such as “BAAD” which presumably indicates a bad MFT entry. The first 4-bytes of a “regular” MFT-entry (or record) starts with the signature “FILE”. These entries are typically 1024 bytes in size, however the size is defined in the NTFS volume header and in a “regular” MFT entry itself. The MFT consists of a sequence of (predetermined) fixed-size entries (or MFT entries). This table is stored in a file system metadata file, meaning that as far as the file system is concerned it is a file, however that the file contains file system metadata not “regular” content. What is $MFT parsing? For readers not familiar with the NTFS file system, MFT stands for Master File Table. Rarely do articles mention the pros and cons of the technique from a digital forensics perspective. Some of these explain the technique itself and others mostly focus on how to use tools. Numerous articles have been written about parsing the $MFT NTFS metadata file before.
