Changes in v1.3.1
Added
- "Always Run as Administrator" toggle added to the Standalone App's File menu. It automatically saves your preference and natively relaunches the app via UAC!
- Live UI Streaming: The Standalone App now populates folders incrementally in real-time as the scan progresses, similar to TreeSize Free.
Changed
- Extreme Performance Optimization: Refactored the core scanning engine to eliminate blocking array allocations and bypass heavy P/Invoke and string operations. SSD scanning speeds have been radically improved, completely resolving UI hangs and slow scans.
- Admin Integration: Restructured the app manifests so that elevated privileges are optional via the UI toggle instead of forcing UAC prompts on every launch.
Fixed
- Command Palette Bug Fixes: Fixed a critical COM marshalling bug that caused the Command Palette to crash when rendering the extension items. Also eliminated duplicate ghost entries caused by identity changes!
