On geogram they are called "collections" because you can synch files/folders with books, games, videos (this is for the prepper world) but it isn't yet working specifically as a sneakernet. This is the basic structure to permit sharing, searching and browsing files: https://github.com/geograms/central/blob/main/docs/collec… I haven't yet ported the collections to the most recent version of geogram but should arrive within a month or so. First solving the topics of bluetooth and radio networks until they are more solid.
