For example, an archive may be called "somefiles.zip—it", which can be opened under any operating system by a suitable archive manager that supports both the file format and compression algorithm used. [2] It may also be converted into somefiles.exe, which will self-extract under Microsoft Windows.

In computer programming, unreachable code is part of the source code of a program which can never be executed because there exists no control flow path to the code from the rest of the program. [ 1 ] Unreachable code is sometimes also called dead code , [ 2 ] [ 3 ] although dead code may also refer to code that is executed but has no effect on ...

On older versions, self-extracting archives were vulnerable to arbitrary code execution through DLL hijacking: they load and run a DLL named UXTheme.dll, if it is in the same folder as the executable file.
