Sergey Grebnov commented on CB-2212:
------------------------------------

Hi Michael, you may try to access the file using XmlHttpRequest

    var xhr = new XMLHttpRequest();

    xhr.open('GET', 'readme.txt', false);
    xhr.onreadystatechange = function () {
        if (xhr.readyState == 4) {
            if (xhr.status == 200) {
                console.log(xhr.responseText);                    
            }
        }
    }

    xhr.send(null);
                
> FileSystem getFile() call never finds file on WP8 as isolated storage is empty

>             Project: Apache Cordova
>          Issue Type: Bug
>          Components: WP8
>    Affects Versions: 2.3.0
>            Reporter: Michael Fry
>            Assignee: Jesse MacFadyen

> In attempting read a file included in my www folder I was continually 
> returned an error code of 0.  In digging in it appears it was due to file not 
> found.
> In the GapBrowser_Loaded handler there is a large chunk of commented out code 
> that notes that in WP8 "isolated storage is no more required in WP8". It 
> appears that this suppresses the loading of isolated storage because when I 
> view my emulator using WP power tools it is empty.
> The file i/o code in File.cs reads/writes using isolated storage.  Without 
> the www files being loaded at startup it will never be able to make the reads 
> from things like settings or readme files.
> After uncommenting the code and creating a CordovaSourceDictionary.xml file I 
> was able to load isolated storage. File reads then worked as designed.
