JqM 1.3.0 problem with local files

JqM 1.3.0 problem with local files

I'm creating some webapp using jqm but when I try to make a cleaner directories layout using html files inside different folders I got problems.
I try to be more specific. I want to use my file in local, people download the zipfile then use it in local.
I already do it but I want to create a multilanguage webapp so I create EN and IT folders I put inside their respective files and on desktop PC it works like a charm but when I test it on my Acer tablet Android based no browser find the files inside the two folders. I tested with UC browser, Boat, Chrome and Opera Mobile.

If I put all html files on the same root level of index.html all works perfectly.
Can someone give me some hints or I give it up and put all html files out like always?

Thanks
Angelo
