This is actually possible. If there is a better way to do this, somebody please let me know.
I put all of the files/folders in /src/rootFolder/ and this moves all of those during dev/build to the / folder when it builds or runs the dev server.
quasar.conf.js , require copy-webpack-plugin up top, then add a line to build.extendWebpack
const CopyWebpackPlugin = require('copy-webpack-plugin');
/// ...
extendWebpack(cfg) {
cfg.plugins.push(new CopyWebpackPlugin([{ from: 'src/rootFolder/', to: '' }]));
/// ...
}
