Monitor the disk for highly used directories?

Did you see this?

Monitor/Alert on folder growth

I did see that but my issue with that is I have to specify a folder to monitor. However since this is a jump box with multiple users folders get created all the time. I was hoping there was like a disk growth monitor to pinpoint large files and stuff. Might be asking for a lot though.

Have you ever used a tool like treesize to browse all the directories and figure out how big they are?  If you have then you might have noticed it typically takes it several minutes, sometimes like 30, to scan a drive.  If you set up a monitor that just browses every folder it could get bad.  A custom powershell script could be put together to just show you the top 3-5 largest folders within users and I bet that wouldn't be too taxing... hopefully.

This powershell blog post could be a good place to start

Thanks Mesverrum this makes sense
