I wanted to take out a very simple report on the largest sub folders in terms of size, for a profile area on a client site

. We have tools to do this, but scripting it was in this case a very quick and dirty way to get the job done
.

This script is reusable on all folders
. It will enumerate the size of the content of all sub folders on the folder on which you run it, measured in megabytes
.

So here’s a little nugget that might help you at the end of backup sessions, or in my case, to adjust for the time zone difference on my vacation after forgetting to check my cameras clock for the entire 2 week duration. Despite it’s simplicity, this script is in fact quite powerful, and if used towards the wrong folder, or with the wrong scope (Get-Childitem -recurse) it can cause a bit of damage.

A fun thing about this script is that by changing the time parameter, you can actually put the Date Modified field into the future without changing the clock on your computer
