None. Everything is compiled into the .EXE file. Of course, if you've
developed other files (like a HLP file, data files, etc.), or if you're
using VBX files, then you have to send them as well. If you use VBX files,
you must also include BIVBX11.DLL.
If the application uses database functions, you also have to include the
Borland Database Engine. You can just distribute the two pre-packaged disks
on the Delphi CD (they don't get installed to your hard drive). And if the
application uses ReportSmith, you have to distribute the ReportSmith run-
time. These are big; the BDE is two disks and ReportSmith is five.
