What do "Up to date", "Changed", "I can't see it" and "No longer there" mean next to each file?
In the side panel, "What I read" shows each file with a label.
In the side panel, "What I read" shows each file with a label. "Up to date": Fold has read it and it hasn't changed. "Changed": you saved a new version and Fold is reading it again. "I can't see it": it isn't in the folder right now; Fold carries on with what it last read and says so in each answer. "No longer there": it has been missing for a few minutes; Fold stops using it and removes it from the list until it is back. Fold keeps its copy for 14 days, and if you only rename it or move it within the folder, it is still the same file. On an installed Fold, the owner also has the list "What Fold reads" in Account › Your data › Privacy: each file by where it comes from (your folder, a cloud folder or uploaded by hand). Next to each file from your folder or uploaded by hand there is "Stop reading", and next to each cloud folder, "Disconnect this folder": Fold stops reading it and sets its copy aside, and your original file is not touched. "Disconnect this computer" is in the same place (see "How do I disconnect this computer from Fold?").
