Ticket came in as "my computer is really slow." Remote user, 256GB laptop. Task Manager normal. Performance diagnostics normal. Then we noticed C: drive: 2.1GB free of 256GB. User had no idea disk was full. Needed to find what was eating 250GB without scheduling a remote session and making user wait while WinDirStat scanned for 20 minutes.

Users almost never connect "disk full" with "computer slow." They see slowness and think virus, bad hardware, or "needs more RAM." The actual problem is their 47GB of vacation videos in Downloads.

Needed something that scans fast, runs silently via RMM, returns actionable output to logs without any user interaction.

Script that downloads gdu (fast Go-based disk analyzer) on-demand, runs parallel scan, outputs largest directories to RMM logs. No pre-installation, no user interaction, results in 30-60 seconds.

What we found: Downloads folder 67GB - five years of installers, zip files, video recordings. AppData\Local\Microsoft\Teams had another 23GB.

Sent user summary email with specific folders to clean. They deleted 85GB themselves, we ran automated cleanup script for the rest.
