Consider easier to read file lengths in directory listings.

Summary of the new feature / enhancement

There have over the years been multiple suggestions for "I think a directory listing should look different" , so I will apologise for adding one. I'm also aware that one can personalize the formatting XML and I have helped other people to do that.
OK.
I bought a new external hardisk and did a backup of my laptop (machine name Elasmo) Here's what I see

How big are the 3 VHDX files ?

Once a number gets beyond half a dozen digits it is really hard to judge the size at a glance. In this case 1298450612224 needs me to count the digits to see it is 1,298,450,612,224 .

The default formatting could include commas, or could change the numbers to read either 1298 GB or 1.3TB (similar to file explorer in Windows) .

Proposed technical implementation details (optional)

Change the formatting XML to either
use "N0" (number separators, no decimals) as the format for the length column
OR
Use a script block to convert numbers above some size to TB, GB etc.

Start by locating the default directory-listing formatting XML and inspect how the Length column is rendered. Compare the proposed N0 number separators with the alternative script-block conversion for large values. Done means directory listings show file sizes that are easier to read while preserving usable column alignment.
