Editing Portable Executable (section)

==Use on other operating systems==
The PE format is also used by [[ReactOS]], an open-source operating system created to be binary-compatible with Windows. Historically, it has also been used by other operating systems such as [[SkyOS]] and [[BeOS]] R3. However, both SkyOS and BeOS eventually moved to [[Executable and Linkable Format|ELF]].{{citation needed|date=March 2021}}

The [[Mono (software)|Mono development platform]], which aims to be binary compatible with the Microsoft [[.NET Framework]], uses the same PE format as the Microsoft implementation. The same goes for Microsoft's own cross-platform [[.NET Core]].

On [[x86]](-64) [[Unix-like]] operating systems, Windows binaries (in PE format) can be executed using [[Wine (software)|Wine]]. The [[HX DOS Extender]] also uses the PE format for native DOS 32-bit binaries, and can execute some Windows binaries in DOS, thus acting like an equivalent of Wine for DOS.

[[Mac OS X 10.5]] has the ability to load and parse PE files, although it does not maintain binary compatibility with Windows.<ref name="chartier">{{cite web|last=Chartier |first=David |title=Uncovered: Evidence that Mac OS X could run Windows apps soon |work=Ars Technica |url=https://arstechnica.com/journals/apple.ars/2007/11/30/uncovered-evidence-that-mac-os-x-could-run-windows-apps-soon |date=2007-11-30 |access-date=2007-12-03 |quote=...&nbsp;Steven Edwards describes the discovery that Leopard apparently contains an undocumented loader for Portable Executables, a type of file used in 32-bit and 64-bit versions of Windows. More poking around revealed that Leopard's own loader tries to find Windows DLL files when attempting to load a Windows binary. }}</ref>

[[UEFI]] and EFI firmware use PE files as well as the Windows [[Application Binary Interface|ABI]] x64 [[calling convention]] for [[UEFI#Applications|applications]].
