Com2exe Utility

The Com2exe utility (COM2EXE.COM) is the developer tool that allows you to convert a DOS COM program to an EXE.


When using the shell protection, the file size of the protected program will be a little bit larger than the original. For a DOS COM program having the file size close to the limit of 64 KB, the shell protection may cause the protected program to have its file size exceed the limit. In this case, you can use the provided Com2exe utility to convert the program to an EXE first, which has no file size limit. This allows you to use ElecKey to protect any DOS program without such restriction.


The Com2exe utility is available in the ElecKey Bin\ folder. Below is the command usage.


Usage: COM2EXE <.COM file>
