Expandable application representation techniques are described. The techniques may include support of an expandable tile that may function as an intermediary within a root level (e.g., start menu or screen) of a file system. The expandable tile, for instance, may be output via a gesture to gain additional information that was not included in an unexpanded version of the tile, may be utilized to provide inputs to an application such that a user, and so on. Thus, this may support non-modal interaction by a user. Techniques are also described in which the expanded representation is included in a taskbar, which may also be used for non-modal interaction, sending of content represented in the representation to a device or application, continuation of interaction initiated with the representation by a mobile computing device, and so on. Expandable tile techniques may also be utilized to support interaction between shells of an operating system, such as a desktop and immersive shell. Further description of these and other examples involving and not involving an expandable tile are also contemplated.
