Defrag 95 is a generative take on the Windows 95 Disk Defragmenter. Every load invents a new fragmented drive and defragments it block by block, with the hum and chatter of a hard drive, synthesized live. Click once to hear it. It touches no real disk.
Is this the real Windows 95 Disk Defragmenter?
No. It is a generative recreation that runs in a web page. It touches no real drive: every disk, file and fragment is invented when the page loads, and nothing leaves your browser.
Why is it different every time?
Every load generates a brand-new imaginary drive. Its size, free space, file lengths, unmovable system files, bad clusters and level of fragmentation are all random, and a real algorithm then defragments it, so no two runs look or sound the same.
How do I get the hard drive sounds?
Click or tap anywhere once. Browsers only allow sound after you interact with the page. The spindle hum, head seeks and read and write chatter are all synthesized live, and you can turn them off in Settings.
What do the colors mean?
Cyan is unoptimized data, blue is optimized data and white is free space. Green blocks are being read, red blocks are being written, maroon with a dot will not be moved, and black with an X marks a bad area of the disk. Press Legend to see them.
What do the three defragmentation methods do?
Full defragmentation puts every file in one piece at the front of the drive and leaves the free space as one block at the end. Defragment files only joins each file's pieces wherever a big enough gap exists, and Consolidate free space only packs the data toward the start without joining files. Pick one in Settings.
Does it keep going on its own?
Yes. When a drive finishes, a new one starts after a few seconds, so it can run for hours. To stop at the end like Windows 95 did, turn off Start a new drive when one finishes in Settings.
Can I make it go faster or slower?
Yes. Press Settings to pick Slow, Normal, Fast or Turbo, and the change applies at once. Press Space to pause and N to start a new drive at any time.
