Disk Defrag Simulator Screensaver
The Disk Defrag Simulator screensaver recreates the classic disk-defragmenter grid, sorting a field of colored blocks into order over and over. It is free, runs in your browser, and ESC exits.
How the Disk Defrag Simulator screensaver works
The saver fills a grid with colored blocks representing simulated fragmented files.
A scanning cursor sweeps the grid, swapping blocks toward a sorted arrangement, exactly like classic defragmenter tools.
Once fully sorted, the grid is reshuffled and the process begins again.
No real disk or files are touched — it is a purely cosmetic simulation.
A worked example
The scanning cursor sweeps left to right, gradually consolidating scattered colored blocks into clean, contiguous bands.
Settings & tips
- Accent recolours the scanning cursor.
- No real disk activity occurs — it is a visual simulation only.
- A nostalgic nod to classic 1990s disk utilities.
