Dr.KBAHT: an e-book about the XM file format specification

{{FormatInfo
|formattype=electronic
|subcat=Audio and Music
|extensions={{ext|xm}}
|pronom={{PRONOM|fmt/323}}
}}

:''Not to be confused with the Sirius XM satellite radio service, with which it has nothing to do.''

'''XM''' (extended module) is an audio format introduced by (and primarily produced by) FastTracker 2, a now defunct tracker for [[MS-DOS]]. The format is also used by other trackers, such as [[DigiTracker]] and [[MilkyTracker]].

== Information ==

The tracker which produced the file can be identified by means of the 20-byte string at offset 38 (0x26):

{| class="wikitable" style="text-align:center; width:200px; height:200px;"
|+ Tracker / Identifying string
|-
!
! String
|-
! DigiTracker
| Composer's name
|-
! FastTracker 2
| "FastTracker II"
|-
! OpenMPT
| "OpenMPT " and then the version number
|-
! AmigaMML
| By default, "AmigaMML " and the version number; can be changed
|-
! MilkyTracker
| "MilkyTracker " (with 8 padding spaces)
|}

Portable Executable

Dr.KBAHT: Import libraries are part of the PE-COFF specifications

'''Portable Executable''' ('''PE''', '''PE/COFF''', '''PE32''', '''PE32+''') is a member of the [[EXE]] family of executable file formats. It is used by the Microsoft Windows family of operating systems (starting with Windows 95 and [[wikipedia:Win32s|Win32s]]), EFI and sometimes in other environments. It is an extension/hybrid of [[MS-DOS EXE]], and a successor to [[NE]]. Parts of it are derived from [[COFF]].

Despite the name, not all PE files are executable. Some contain only icons, fonts, etc.

== Formats ==
* '''PE32''' format is used by 32-bit Windows.
* '''PE32+''' format is used by 64-bit Windows.

== Identification ==
A PE file begins with the ASCII signature "<code>MZ</code>". At offset 60 is a 4-byte integer pointing to an "extended" header that begins with <code>'P' 'E' 0x00 0x00</code>. For more information, see [[MS-DOS EXE]].
