Finding largest files

Question

Hi Guys,
I have a situation where i  have multiple home drives on a share. i want to list their largest (size) files with their parent folder names (this usually is their username), so i know which user is consuming more space and also it would be good to point
out their largest files so they can either delete or other arrangements are organised. It would be nice to get a spreadsheet with the results.
I know it can be done with each of those homedrives which is time consuming task and i know powershell can do that quicker so i hope some has an answer!

Thanks very much for the replies. Following is the script which basically scans all the "Home Drives" and produces a nice list with the name/location and size. with that i can find out who is using most of the space.  
function Get-FolderLength
# Usage: Get-FolderLength.ps1 D:\Homedirs
param ( [Parameter(Mandatory=$true)] [String]$Path )
$FileSystemObject = New-Object -com Scripting.FileSystemObject
$folders = (Get-Childitem $path | ? {$_.Attributes -eq "Directory"})
foreach ($folder in $folders)
$folder | Add-Member -MemberType NoteProperty -Name "SizeMB" –Value(($FileSystemObject.GetFolder($folder.FullName).Size) / 1MB)
$folders | sort -Property SizeMB -Descending | select fullname,@{n=’Size MB’;e={"{0:N2}" –f $_.SizeMB}}
That scripts only scans the Directories. Next i would like to scan each of those home drives and list only top 10 or 20 biggest files. so i can inform users about those big files. 
Example: 
Directory 1 
Directory 2
Directory 3
Directory 4
i want to scan each of those directories to find which files are using most space. A nice output with directories names and most space consuming files would be great (csv).  
Any help would be much appreciated!
