If you set in Preferences the "Update sketch files to new extension on save" and open a sketch that is a .pde and just do a "save" and then build. You will get an error that the .pde can't be found. I believe that is because the file was a .pde when opened, but when the save occurred the IDE did not switch the build from a .pde extension to a .ino extension and still attempts to compiler the .pde instead of the renamed .ino. Restarting the IDE solves the problem.
