Another question...
According to what you said, if I'm not using Nodewebkit the filesystem api will not work (that's what I understood). In other words, if I try to create a HTML5 application able to read a directory (the project directory) I will have to use the nodewebkit? Is there a chance to just preview in nodewebkit and then add the node.js library to the application and run it in every browser?
Thanks for your answer in advance, again.
