An illustration of the linking process. Object files and static libraries are assembled into a new library or executable. A linker or link editor is a computer program that combines intermediate software build files such as object and library files into a single executable file such a program or library.
Executable compression used to be more popular when computers were limited to the storage capacity of floppy disks, which were both slow and low capacity media, and small hard drives; it allowed the computer to store more software in the same amount of space, without the inconvenience of having to manually unpack an archive file every time the ...
Executable code, an executable file, or an executable program, sometimes simply referred to as an executable or binary, is a list of instructions and data to cause a computer "to perform indicated tasks according to encoded instructions", [1] as opposed to a data file that must be interpreted by a program to be meaningful.
Early compilers and linkers for the MS-DOS platform could not produce a COM file executable directly. Instead, the compilers would output an EXE-format file with relocation information. If all 8086 segments were set to be identical in such an EXE file (i.e. the "tiny" memory model was used), then exe2bin could convert it to a COM file.
Zero-byte files may arise in cases where a program creates a file but aborts or is interrupted prematurely while writing to it. Because writes are cached in memory and only flushed to disk at a later time ( page cache ), a program that does not flush its writes to disk or terminate normally may result in a zero-byte file.
During the software development cycle, programmers make frequent changes to source code. When using a compiler, each time a change is made to the source code, they must wait for the compiler to translate the altered source files and link all of the binary code files together before the program can be executed. The larger the program, the longer ...
Executable files stripped of such context are far more challenging to translate into meaningful source code. Some software developers may obfuscate, pack, or encrypt parts of their executable programs, making the decompiled code much harder to interpret. These techniques are often done to deter reverse-engineering, making the process more ...
A dumper is a program that saves data from the computer's memory, usually from a foreign process to a (*.dmp) file. Often the process's memory is dumped automatically to disk if the program crashes. You may recover any unsaved data from this file or send it to the developer so he can investigate what caused the crash.
