Junk Yard · Cards, notes and editing
What does Embed file do in the Junk Yard?
Short answer: Embed file puts a reference to a file you pick onto the board. The card opens or copies the real file, takes no extra space, and follows the file if Storage Studio moves it.
Embed file drops a reference to a file you choose onto the board, without you having to copy it first. Like any file scrap, the card shows the file's icon and name, opens the file when clicked, and copies the real file when you use Copy.
It's a reference, not a copy, so it takes no extra space — and if the original is moved by Storage Studio the card follows it.
