.XOJO_WINDOW File Extension
What is a XOJO_WINDOW file?
Window file created by Xojo, an IDE that enables users to create custom applications; used to share a window in the Xojo project (text) format; includes information, such as window behavior, minimum window size, and background color; 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_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_WINDOW file, select File → Import, navigate to your file location, and click Import.
NOTE: REAL Software Real Studio became Xojo, Inc. Xojo in 2013.
