A free, browser-based simulator of the classic Microsoft Windows 98 Disk Defragmenter. Pick a drive, cue the hard drive sounds, and relive the nostalgia of watching your disk defragment, just like the good old days of 1998.
Watch the familiar grid of colored clusters rearrange itself in real time as fragmented data is consolidated into one contiguous block, complete with authentic period hard-disk sound effects. Choose from four virtual drives — C, D, E and F — ranging from 512 MB to 2 GB and from slow, grinding hard disks to a zippy late-90s drive.
Defrag98 is a nostalgia simulator only. It runs entirely in your browser, works offline as an installable web app, and never reads, moves or modifies any real files on your device.
