Error publishing HTML 5 project

[Gray Susan]

Keep receiving the following error message when trying to publish a project.

Could Not Copy Folder to <C:\Users\cp6669\Desktop\AVI-17 Avionics Phase Review III \assets>

This is the first time trying to publish this project.

Is this the normal path... looks weird. Please avoid spaces and '-' in names.

Try publishing to a different folder. Make sure the published output from that folder is not already open in a web browser when trying to republish.  That will sometimes be the problem.
