pCloud

pCloud's central idea is pCloud Drive: a mounted virtual disk that appears as a drive letter or volume, streaming files on demand without consuming local space. You browse it like any folder, and files download as you open them. This makes large libraries feel resident without the storage cost, and it's the cleanest expression of the mount-don't-sync model. The desktop app wraps this with a tabbed interface for sync pairs, shared links, and a built-in player for media stored in the cloud. The web app is serviceable but plain. Where it stumbles is feedback during partial downloads and spotty offline behavior; a half-streamed file can fail in ways the UI explains poorly. Still, the mounted-drive metaphor is its sharpest, most coherent interaction.
