Did you know there are some packages on your Synology NAS that will use up more space than expected? You might notice this when you see your storage space on the disks is unexpectedly full, but you are unable to find where exactly the issue is with the full space on your disks. Today I will teach you how to see the full volume usage details to help you better understand the current usage of a volume. The information that is calculated allows you to find out which service specifically occupies the largest storage capacity and take corresponding actions, for example delete unnecessary data.

Note: The usage detail analysis of a volume is only supported on BTRFS volumes not EXT4.
