Window file created by Xojo, an IDE that enables users to create programs; replaced the .RBW file extension used to share a window between Xojo projects; saved in the Xojo XML format; includes information that describes aspects of the window, such as buttons, custom backdrops, and frame type.

Xojo projects can be saved in three different formats: Project (text), Binary, and XML. The selected format dictates the window format. If you do not have a product license, you will only be able to export a window as a .XOJO_BINARY_WINDOW file, which closely resembles the old Real Studio binary format. To create the XOJO_XML_WINDOW file, click the window you want to export, select File → Export [window name]..., choose the save location, name the file, and click Save. To import the XOJO_XML_WINDOW file, select File → Import, navigate to your file location, and click Import. NOTE: REAL Software Real Studio became Xojo, Inc. Xojo in 2013.
