Works perfect on two of four devices.

[qroft]

Expected Behaviour

a) Download a zip file, extract it and save it to the cordova.file.dataDirectory
AND
b) Check if a folder on the external (emulated) storage exist

Actual Behaviour

On two devices everything works fine.
On the other two neither can i
a) download a ZIP file (no error but does not even start a download)
AND
b) I can not even check if a folder exists with
$(".butCheckFolder").click(function(){ store = cordova.file.externalRootDirectory; window.resolveLocalFileSystemURL(store + "gifs", function () { $('.butCheckFolder .item-title span').html('Folder found.'); }, function (error) { $('.butCheckFolder .item-title span').html('Folder not found.'); }); });

Reproduce Scenario (including but not limited to)

Use the standard example, but on different devices.
Try one that has no SD card mountable for example.
