Where are my Studio projects and recordings stored?

On your computer only: %APPDATA%\ScriptFox\recordings\ has one folder per project with the screen, webcam, and mic tracks plus the project file; nothing is uploaded. Exports default to Videos\ScriptFox Screen Recordings. In the Studio, File → "Open recordings folder" opens the projects folder, and a library card's "Reveal in folder" opens that project. Deleting a project from the library frees its space (the preview caches can be large). Projects don't sync to other PCs; back up the recordings folder if you want to keep them.
