Windows Phone 8.1 may already have two 3rd party file managers like Aerize Explorer and Pocket, but Microsoft’s Joe Belfiore has leaked news that an official file manager is in the works and should be out by end of May. His words:
*** YES *** We are doing a File Manager for WP8.1! I know a LOT of you are looking for this (thanks for the tweets, I’ve read them all). In fact, I’ve been running a build of it on two of my phones for the last week or so and it’s getting to pretty good shape.
Here’s what it looks like: http://imgur.com/a/hvqGD#nRuOFXp
We are expecting to get it into the store HOPEFULLY by the end of May.
From the published images, the official WP8.1 file manager will let users access folders and files on both the device and memory card, move files, as well as create new folders.
