Relive 1998: Windows 98 Disk Defragmenter Simulator Now Runs in Your Browser
Defrag98: Windows 98 Disk Defragmenter Simulator Online
Defrag98 is a free, browser-based simulator of the classic Windows 98 Disk Defragmenter. It recreates the iconic grid of colored clusters, complete with authentic hard-disk sound effects, and lets you choose from four virtual drives with varying speeds. It's pure nostalgia—no real files are touched, and it works offline as an installable web app.
Watch the familiar grid of colored clusters rearrange itself in real time as fragmented data is consolidated into one contiguous block.
