I have been following this tutorial on how to export an app to appmobi: http://www.scirra.com/tutorials/304/how-to-export-to-appmobi-with-directcanvas/page-1
But when i get up to the bit where i export the files into the 'Documents\AppMobi XDK\MyCompany.MyProject\3.4.0\' I cannot find such path even though i have not modified anything.
Though i did find a file called _xdk_analyctics and it had a folder which was named myproject which is the project name i created for it. So i exported the files to there though it won't show up on the simulator when i refresh it.
Are you sure you looked in the XDK projects folder, that you created the project correctly, and that you looked for a folder with the name of the project you created? Maybe searching your computer for the project name will help you find it.
It sounds like there was an error creating the project. The _xdk_analytics directory should include a similar "MyCompany.MyProject" directory, but the appropriate "MyCompany.MyProject" folder should be in the same directory as _xdk_analytics.
Have you tried to create a new project? Did that create the directory? Perhaps there is a permissions issue on your computer?
