A Windows 98-inspired incremental game: move your mouse across fragments, hear them click into place, and spend your earnings on a bigger, faster defragmentation machine.

• Duplicate files on D3, ransomware on D5, timed challenges from D4, replays and Casual mode.
• Daily disk: a fixed-seed timed challenge each day, with a personal best and streak. Open Extras from My Computer.
• 11 in-game achievements in the demo, saved locally.

How to play

Move the mouse to read fragments automatically; no need to hold a button. Buy upgrades with earned bytes. D1–D3 keep board progress; failed timed challenges keep earnings and upgrades. Unlock Active Cooling for upgrades during a run.

U: upgrades · Esc: pause · Space / Enter: confirm. Use the embedded player's fullscreen button. Desktop browser and mouse recommended.

Full game feature overview — Steam version in preparation

The web demo ends after D5. The overview below describes the full game. D6–D10, the complete endings, reinstalls, BIOS boosts, challenge modifiers and commissions are not included in this browser demo. The trailer also previews later full-game disks, marked in the video.

You watched it as a kid. Now it's your turn.

Disk Defragmenter is a nostalgic, Windows 98-inspired incremental game. Move your mouse, and wherever the read head passes, fragments fly back where they belong. The messy disk slowly turns into neat bands of color as fragmentation drops from 37% to 0%.

Every sweep pays off

Each block that snaps into place clicks and earns space. Finish a file and its whole band lights up, the drive cools down, and you can keep sweeping. No need to hold a button. Just move.

Upgrades you can feel

A bigger head, more read channels, background auto-cursors, and a right-click that sorts a whole file at once. On the same disk, you start reading one block at a time and end up clearing huge areas in a single pass.

Timed challenges from the fourth computer

Finish before the clock runs out to clear the disk. Fail, and you keep your earnings and upgrades, so you can come back stronger. Return to old disks to beat your best time and earn stars. Prefer no pressure? Enable Casual mode in Settings; it takes effect the next time you enter a disk.

Ten computers, thirty years of one life

A 1998 floppy, the family's first PC, a dorm laptop, a first work computer, your parents' old desktop... All 80 files you recover can be opened: chat logs, exam results, a wedding guest list. Together they tell the story of an ordinary life, and end with a letter to the future.

New trouble on every machine

Duplicate copies, ransomware, burst photos, spreading bad sectors, a mirrored head, master indexes and three-generation partitions. Seven unique mechanics keep later disks from simply getting bigger.

After the ending

• Reinstall the system: keep your recovered files and spend restore points on permanent BIOS boosts to make the next run faster.
• Challenge modifiers: make a run harder on purpose, such as No Assistants, In a Hurry or Tight Budget, to earn more restore points.
• Daily disk: one fixed-seed timed disk every day. Chase your best time and your streak.
• Commissions: after the ending, fix six friends' computers, each with a short story of its own.
• Achievements: 23 in-game achievements track your defragmenting journey.

Features

• 10 disks, 12 upgrades, 7 unique mechanics
• 80 readable story files in English and Chinese, two endings
• System reinstalls with 10 permanent BIOS boosts for faster repeat runs
• Daily disks, commissions and 23 achievements
• English and Simplified Chinese, matched to your system language
• Mouse-only play, with fullscreen and windowed modes (F11 / Alt+Enter)

This is only a game. It never scans or defragments your real files; it only saves game progress and settings.

U：升级 · Esc：暂停 · 空格 / 回车：确认。用网页播放器的全屏按钮放大画面；推荐桌面浏览器与鼠标。

正式版完整介绍｜Steam 版筹备中

网页试玩在 D5 后结束。下文介绍正式版整体内容；D6–D10、完整结局、重装、BIOS、挑战修饰和委托不包含在本页试玩中。宣传视频也有后期正式版磁盘，相关镜头带有范围标注。

小时候看它整理，现在轮到你了。

《磁盘碎片整理》是一款 Win98 风格的怀旧增量游戏。移动鼠标，磁头扫过哪里，那里的碎片就飞回原位。乱糟糟的盘面一点点排成整齐的色带，碎片率从 37% 一路降到 0%。

扫过去就有反馈

每一块碎片归位都有咔哒声、有收入。拼完一个文件，整条色带亮起，温度降下来，还能再多扫一会儿。不用按住鼠标，移动就行。

越升级越快

更大的磁头、更多读取通道、后台自动光标、右键一次整理整个文件。同样一张盘，开局一次只能读一块，后期一扫就是一大片。

从第四台电脑开始限时

倒计时里完成整理才算通关。没过也不亏，赚到的字节和升级都会保留，升级后再来；回到旧盘还能刷新最佳用时和星级。不想赶时间，可以在设置中打开休闲模式，下次进入磁盘时生效。

十台电脑，一个人的三十年

1998 年的软盘、家里第一台电脑、大学宿舍的笔记本、第一份工作的电脑、爸妈家的旧电脑……整理好的 80 份文件都能打开，聊天记录、成绩单、婚礼宾客名单，慢慢拼出一个普通人的人生，以及一封留给未来的信。

每台电脑都有新麻烦

重复的副本、勒索病毒、连拍照片、扩散的坏道、镜像磁头、母带索引和三代分区。七种专属机制，让后面的盘不只是变大。

通关以后

• 重装系统：保留找回的文件，用还原点购买 BIOS 永久加成，下一周目更快。
• 挑战修饰：重装时自愿加难，例如禁用助手、赶时间、预算紧张，换取更多还原点。
• 每日种子盘：每天一张固定盘面的限时盘，挑战自己的最佳用时和连续天数。
• 委托：看完结局后，帮六位朋友整理他们的电脑，每单都有一段小故事。
• 成就：23 项游戏内成就，记录你的整理旅程。
