Microsoft's Windows Phone leader Joe Belfiore made a significant announcement during his Reddit AMA session today, and it's one that's been a long time in coming. A File Manager feature will be added to Windows Phone 8.1 in the near future. He even provided some screenshots which were uploaded to Imgur. The images show that users will be able to create new folders from within the operating system and search inside folders for specific documents. It will also allow users to move folders to an SD card. The File Manager feature is scheduled to be released for Windows Phone 8.1 users sometime before the end of May, according to Belfiore. It certainly will be a huge new addition for people who use the OS.
