Tune the simulation in detail
Change fragmentation, virtual drive size, grid resolution, speed, scatter, and block movement, then observe the effect without leaving the same simulation.
Open appDefrag: complete feature guide
This guide brings the full scope of Defrag together in one place. Open any section for a practical explanation of the capability and its options.
Assemble an image from drive blocks
Upload or paste a photo, choose a built-in motif, enter short text, or draw a pixel target. The moving blocks gradually reconstruct that image.
Open appSix visual identities for one process
Switch among Classic95, text mode, system utility, modern glass, light acrylic, and smartphone themes. Presentation changes while the simulation itself stays the same.
Open appDrive sounds and note sequences
Choose a timed audio profile for floppy, HDD, SATA SSD, or NVMe behavior, and optionally let a sequence of notes turn the activity into a melody.
Open appShare a link that restores the state
A compact link carries the configuration plus its motif or compressed block image. Opening it restores the setup and automatically starts the simulation.
Open appExport the completed grid as PNG
Once ordering finishes, save the final block grid as a PNG image and keep the picture assembled by the defragmentation process.
