Can I write some data to SD card on Windows Phone 8

Question

I checked Windows Phone 8 SDK document, and find that we can read the data from SD card, but we can\'t write something to it, is my understanding right?

Answer 1

Third party applications cannot write directly to anything outside the application's IsolatedStorage.

Answer 2

UC browser is able to export files to the sd card though. I think they have access to an extended API not available to regular developers, I've tried reaching out to them as to how they did it but so far I have not got a reply. So, yes it is possible, but the clever hack or method implemented by them is not public. Here is some more information, http://forums.wpcentral.com/windows-phone-8/266236-developers-given-access-sd-card.html

Answer 3

You can get read-only access to specified files on SD cards using the ExternalStorage API and ID_CAP_REMOVABLE_STORAGE capability, but you cannot write to this storage.
