Find largest files in directory and delete them

Hi,

I'm looking for a Powershell script dat finds the three largest files in a directory tree and delete these files. I found a script that lists those files, but how to delete them?

Here is what I got so far;

gci E: -r| sort -descending -property length | select -first 3 name, @{Name="Gigabytes";Expression={[Math]::round($_.length / 1GB, 2)}}

Thanks!
