qip_path in Megawizard?

It was never my desire to change the value of qip_path, only to set it to the required value, pointing to the directory where my .vhd files live. Without setting it I was getting error messages from the Quartus fitter that the .vhd file could not be located.

I did not realize that adding the directory for the .vhd files as a library in Settings would accomplish this. I have not tried it yet, but will do so in the next 24 hours.

There is absolutely nothing useful in Quartus Help on the subject of qip files...
