keybase allows users to store up to 250 gb of files in a cloud storage called the keybase filesystem for free. there are no storage upgrades available, however paid plans allowing for more data are planned. the filesystem is divided into three parts: public files, private files, and team files. on unix-like machines, the filesystem is mounted to codice_1, and on microsoft windows systems it is usually mounted to the k drive. currently, mobile versions of the keybase client can only download files from kbfs, and can not mount it. however, they do support operations such as rekeying files as necessary. in october 2017 keybase brought out end-to-end encrypted git repositories.
