I recently faced a situation where the free space on my laptop disk was suddenly depleted. After some searching, I found that PowerGUI keeps its scripteditor logs at “C:Users<username>AppDataLocalQuest SoftwarePowerGUILogs”. If you use PowerGUI a lot, you might experience a slow but steady exhaustion of disk space due to seemingly orphaned log files in that folder.
If you are like me, you may want to keep cleaning out this folder to keep space available.
