How do I see how much space old versions use in Delta Drive?
Short answer: The Versions screen shows how many old copies exist, their space and age, and which files hold the most history. It counts daily; Count them now updates it immediately.
Open Versions in the Delta Drive sidebar. It shows how many old copies exist, the space they use and how far back they go, and lists the files holding the most history.
Counting runs once a day; Count them now does it on the spot. If your history has never been counted, the screen says so rather than showing zero. If it's larger than one pass can count, the figures are marked as lower bounds (at least).
