Your composition can open files on your computer’s filesystem or download them from the internet using “fetch” nodes, such as Fetch Image, Fetch Data, and Fetch XML Tree.
Your composition can save files to your computer’s filesystem using “save” nodes, such as Save Image, Save Data, and Save Images to Movie.
For opening, manipulating, and saving XML and JSON files, there’s the vuo.tree node set. And for CSV and TSV files, there’s the vuo.table node set.
The vuo.file nodes enable your composition to interact with your computer’s filesystem.
