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

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 save in the binary format, which closely resembles the old Real Studio binary format. To create the XOJO_BINARY_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_BINARY_WINDOW file, select File → Import, navigate to your file location, and click Import. NOTE: REAL Software Real Studio became Xojo, Inc. Xojo in 2013.
