Question

Hi I have to read some files from an mobile app (html5, Phonegap).

How to point my app to the root directory of my device. With root I mean the dir that I see when I open “my files” app?

I think what you’re looking for is window.requestFileSystem:

    window.requestFileSystem  = window.requestFileSystem || window.webkitRequestFileSystem;
    window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, gotFS, fail);

And:

    fileSystem.root.getDirectory(window.appRootDirName, {
        create : true,
        exclusive : false
    }, dirReady, fail);
