Hi,
Sorry, I just checked the full ZIP and there are no .HPP files. I didn't delete anything in the smaller ZIP except:

*.~* (e.g. file.~cpp, file.~h, etc... since these are temporary files)
*.o (generated when you compile)
*.tds (debugger symbols, generated when you compile)
(possibly), *.obj (not sure - might be generated when you compile)
*.exe (generated when you compile)
PICBOOT.dll (available from binary distribution)

Everything else is still there It looks like the source I have is incomplete.
