Defrag98: Windows 98 Disk Defragmenter Simulator Online

Defrag98 is a free, browser-based simulator that recreates the classic Windows 98 Disk Defragmenter experience with authentic visuals and hard-drive sound effects. Users can select from four virtual drives of varying sizes and speeds to watch a nostalgic animation of disk defragmentation without any actual files being affected on their devices. The simulator runs entirely in browsers, functions offline as a web app, and is designed purely for nostalgia purposes.
