What's the difference between the COM and EXE extensions? | |

Raymond Chen: Commenter Koro asks why you can rename a COM file to EXE without any apparent ill effects. (James MAstros asked a similar question, though there are additional issues in James' question which I will take up at a later date.) Initially, the only programs that existed were COM files. The format of a COM file is... um, none. There is no format. A COM file is just a memory image. This "format" was inherited from CP/M. To load a COM file, the program loader merely sucked the file into memory unchanged and then jumped to the first byte. No fixups, no checksum, nothing. Just load and go. | ||
