Read file objects and their selected properties

A cmdlet is a PowerShell command. An object is a structured value with
named properties; Name and Length are file-item properties. Selecting
a property is different from finding text in a line. The display below
is a conceptual example rather than an actual folder observation.

Fixed folder contains alpha.txt, beta.txt and a subfolder drafts.
Get-ChildItem -LiteralPath . -File | Select-Object Name
Predicted display (order/format may vary):
Name
----
alpha.txt
beta.txt
Pipeline passes file objects; Name is a property. drafts is a directory
and excluded by -File. No file is changed by this listing.
Separate question pipeline: Get-ChildItem -File | Select-Object Length
Which shell passes objects with named properties? PowerShell or cmd
