The article is devoted to the search and analysis of forensic information at the file system level. The paper considers some basic concepts, data structures and principles of operation of one of the most common file systems New Technology File System (NTFS), which is the standard for operating systems of the Windows family. Authors analyzed the structure of the main attributes, such as $STANDARD_INFORMATION, $FILE_NAME, $OBJECT_ID and $DATA. An experiment on decoding a file record in the Master File Table (MFT) is described, during which information was obtained that allows identifying a file. This method can also be applied when recovering deleted or damaged data.
