Listing can contain standard file information like file name, extension, type, owner and date created, but especially for forensic analysis file meta data can be extracted from various formats: 1) executable file information (EXE, DLL, OCX) like file version, description, company, product name. 2) multimedia properties (MP3, AVI, WAV, JPG, GIF, BMP, MKV, MKA, MPEG) like track, title, artist, album, genre, video format, bits per pixel, frames per second, audio format, bits per channel. 3) Microsoft Office files (DOC, DOCX, XLS, XLSX, PPT, PPTX) like document title, author, keywords, word count. For each file and folder it is also possible to obtain its CRC32, MD5, SHA-1 and Whirlpool hash sum. Extensive number of options allows to completely customize the visual look of the output. Filter on file name, date, size or attributes can be applied so it is possible to limit the files listed.

File Format Identification is the process of figuring out the format of a sequence of bytes. Operating systems typically do this by file extension or by embedded MIME information. Forensic applications need to identify file types by content.

Tools

libmagic

  • Written in C.
  • Rules in /usr/share/file/magic and compiled at runtime.
  • Powers the Unix “file” command, but you can also call the library directly from a C program.
  • http://sourceforge.net/projects/libmagic
