.XOJO_PROJECT File Extension
What is a XOJO_PROJECT file?
Project created by Xojo, an IDE used to create desktop, web, and console applications; can be built into an executable file; contains data in the Xojo project (text) format that references the contents of the application; includes windows, menus, and build settings.
Xojo projects can be saved in three different formats: Project (text), Binary, and XML. If you do not have a product license, you will only be able to save your project in the binary format (.XOJO_BINARY_PROJECT), which is similar to the old Real Studio binary format.
To create the XOJO_PROJECT file, select File → New Project..., name the application, click "OK." After you create the project, select File → Save As..., choose the save location, and click Save.
NOTE: REAL Software Real Studio became Xojo, Inc. Xojo in 2013.
