-Since Docker does not yet support resizing docker containers, OpenPanel uses storage files that can be extended or shrunk on the fly.
 
 *Disk Usage* section displays real-time disk usage for a user: 
 
 - `/home/username` is used for all website files that user uploads to their home directory.
 - `/var/lib/docker/devicemapper/mnt/..` is the total file system that the user's Docker container is limited to; this includes the OS itself, system services, databases, logs, etc.
