hello everyone： Syncthing Configuration -> Folder Element -> minDiskFree Accepted units are % , kB , MB , GB and TB . Set to zero to disable. What does % mean ？ Byte？

% means exactly that: percent of disk space. Say you have a 500 GB disk and set the value to 10 %. Syncthing will try hard to make sure at least 50 GB is left free.
