First project
New, save, save as, and the image / font folders.
Menu File → New / Open / Save / Save as. The project file is .uiproj. After it opens, see Main window layout.
Suggested layout

├── image/
└── font/Save vs save as
| Action | Result |
|---|---|
| Save | Stores absolute image paths; does not force a copy into image/ |
| Save as | Copies images to the target image/, packed fonts to font/, and writes relative names |
| Open | Prefers absolute paths; if missing, looks in image/ next to the project |
| Undo history | Not stored in the project; it is gone when you quit |
When you send a project to someone else, Save as into a new folder and zip it together with image/ and font/.
Auto-recover
Unsaved dirty projects go to %LocalAppData%\RUI_Studio\AutoRecover\ on this PC. After a crash, the next launch may offer to restore. Choosing No clears those drafts.
