The Keybase filesystem (KBFS) is a distributed filesystem withĮnd-to-end encryption and a global namespace. Among other things, that means that by default files on “Filesystem” means that there is no sync model - files stream in and “Distributed” means you can access it from any device. The local disk for temporary and transient data see the "Local disk KBFS don’t permanently take up space on your devices. "Syncing data for offline access" section below for more details.)
