Questions tagged [filesystem]
The general filesystem in Ubuntu is arranged in a single tree with everything under /. This tag should be used for questions dealing with Ubuntu's layout of files, permissions, and files that reside in special locations on disk. Questions related to a particular filesystem should instead use the specific tag for that (for instance: ext4, btrfs, zfs).
