Delta Drive, Delta Trust & My Drive · Delta Drive on your Mac
Why does Delta Drive show my folder straight away and then update it?
Short answer: Delta Drive shows the folder you last saw at once, then checks it with the drive. Returning to the window refreshes a folder older than a minute, so changes from the web or another Mac appear by themselves.
So you're never left waiting on "Reading your drive…". Delta Drive shows the folder you last saw at once, then checks it with the drive and updates anything that changed.
Coming back to the Delta Drive window refreshes the folder on screen when it's more than a minute old, so changes made on the web or another Mac appear without clicking around. Switching away while it's still opening doesn't stop it loading, and a brief network blip is retried rather than failing the read.
Files you open are kept on your Mac and show Ready to read, so they open straight away next time if they haven't changed. If a listing still looks wrong, see the repairs in the gear menu.
