Osenpa Disk Analyzer release notes

What changed in each version, from newest to oldest.

Version 1.1.2 Latest

A smaller download with faster drive scans and smoother interaction while scanning and browsing results.

Significantly reduced application package and download sizes.
Increased drive-scanning speed and accelerated scan-result preparation.
Improved scan progress animations and interface responsiveness during scans.
Made mouse-wheel scrolling smoother in long file and folder lists, reducing lag and stuttering.
Reduced repeated processing when refreshing result rows.

A quieter disk-analysis experience with updated runtime components and preserved settings.

Automatic Store review and donation reminders have been removed. The Donate button remains available for optional support.
The bundled .NET runtime has been updated to 8.0.31.
Existing application settings remain compatible. A portable EXE is available alongside Microsoft Store.

This release makes multi-drive scans more reliable and gives you clearer filters, removable-drive handling and fail-closed cleanup controls.

Use MFT scanning on supported NTFS volumes and a compatible folder-scan fallback elsewhere.
Coordinate Scan All work so stale progress or late results cannot replace a newer scan.
Keep the last valid result when a newer scan is canceled, fails or becomes stale, including work with removable drives.
Clean only allowlisted cache and temporary-file locations, stop when a safety check fails and review the cleanup receipt.
