A formatting view file is a PowerShell configuration file that defines how objects are displayed in formatted output.

How it is used
Improves PowerShell tool output by defining polished default views for custom object types.
How deep it goes
Explains XML structure, type selection, table columns, labels, widths, alignment, and column-count failures; it remains tutorial rather than comprehensive.
Examples
Uses Microsoft’s core format definitions, DiskInfo and MachineInfo table views, revised tool code, and a module manifest.
What you can do after
Build it from scratch by copying a table view, assigning a custom type name, mapping properties, and packaging the view with a module.
