A version of the Windows 3.1 Help Compiler which has been enhanced to use extended memory is now available in the Microsoft Download Center. The extended memory version of the Windows 3.1 Help Compiler (HCP.EXE) generates files for the Windows 3.1 Help application. As with all previous versions of the Windows Help Compiler, the new version runs under MS-DOS. However, the new version requires extended memory and is best run in an MS- DOS session under Windows.

The size and complexity of the files processed by earlier versions of the Windows Help Compiler is constrained by the amount of free MS-DOS memory available at compile time. This capacity constraint has caused difficulties for some developers creating very large files for Windows Help. The HCP.EXE application removes this capacity constraint.
