File Manager Blue is a free app that provides a file manager with more features than, and a different look from, the classic Windows Explorer that's become a mainstay of desktops and devices everywhere. On mobile devices in particular, Windows Explorer starts to show a few flaws, but Blue is designed with those devices (or at least tablets) in mind, from its shape to its features.
A Blue Letter Day
Perhaps most notably, File Manager Blue allows users to draw on and share pages using Microsoft Ink. This means that devices with styluses, like tablets, are uniquely posed to take advantage of Blue's features, which allow file lists to be shared with colleagues for example. Blue also excels in moving large batches of files from multiple folders to one central folder, and in other business uses where Explorer and its ilk are serviceable but not great.
On the flip side, for home users or those who don't work in IT, Blue's very blue interface will be difficult to deal with. It resembles a BIOS or other highly-textual interface from the mid-90s, and doesn't offer file previews or many other modern bells and whistles. As such, File Manager Blue is an excellent choice for power users who have a lot of file management operations to perform, but it isn't a great choice for many typical users who just want to browse files from day to day.
