Quick answer
What is Osenpa Disk Analyzer best for?
Osenpa Disk Analyzer is a free Windows storage tool for people who need to find large files and folders before moving, archiving, or deleting data. It scans local drives on Windows 10 or 11, supports fast NTFS analysis and guarded temporary-file cleanup, and keeps file lists on the PC. Users should review personal files before deleting anything.
What's new in Osenpa Disk Analyzer 1.0.2
Osenpa Disk Analyzer 1.0.2 Highlights
Version 1.0.2 improves startup behavior, window-size memory, Store support, permissions clarity, portable EXE packaging, and small-window dialog readability while keeping disk analysis local.
Better Startup Window Behavior
The app no longer starts full screen on first launch. It opens centered with an ideal window size, then restores the last window size on future launches.
Store Review Support
Donate now includes a Microsoft Store review option so Store users can support Osenpa by rating the app.
Clearer Permissions Explanation
The About > Permissions section now explains MSIX and administrator permission behavior more clearly.
Portable EXE False-positive Reduction
Disk health checks were removed from the portable EXE to reduce the risk of false-positive detections by security tools such as Kaspersky.
Portable Packaging Adjustment
The portable EXE remains a single file, but single-file compression is now disabled for a more transparent packaging profile.
Small-window Dialog Polish
Popup and dialog text visibility was improved at smaller window sizes, with additional stability and visual compatibility checks across the app.

How to review storage without deleting the wrong files
Scan the drive or folder that is low on space, sort by size, and inspect the largest folders before opening individual files. Large virtual machines, application data, photo libraries, games, archives, and system components may be legitimate. Confirm paths before moving personal files, review every temporary-file selection, keep backups, and uninstall applications through Windows instead of deleting unfamiliar program folders.
