Disk Usage

✓ functional

Size every database on the instance, plus the current database's file layout.

Opened from a server, Disk Usage gives you the whole instance: a Databases tab that sizes every database - largest first - plus, on SQL Server, a Files tab for the current database's file layout. The columns follow what each engine can actually report:

SQL Server - name, state, recovery model, data MB, log MB, and file count per database.
PostgreSQL - name, owner, and size; databases your login cannot connect to show an honest blank instead of a guess.
MySQL / MariaDB - data, index, and free space per schema, with table counts.
SQLite - the file itself: size, reclaimable space, page count, and page size.

Scope-aware. This is the server-wide view. Open Disk Usage from a single database instead and it drops the all-databases tab and shows only that database's files. See Disk Usage (database).

SQLly server-scoped Disk Usage listing all databases — Server Disk Usage: the Databases tab sizing every database on the instance.

Read-only - this pane only observes sizes and growth settings; it never changes them.
